Marktech Expands their Multi-chip Product Line with Multi-Wavelength SWIR LEDs and a 2.6µm InGaAs Detector in One Package

Marktech’s Next Gen Hermetic SMD ATLAS Packaged InGaAs Detectors

Marktech MTMD34679PD6T38 – SWIR multi-chip emitter-detector with multiple wavelength LEDs

April 23, 2024 – Latham, NY, USA – Marktech Optoelectronics, Inc. (www.marktechopto.com)(Marktech), a privately-held leading designer and manufacturer of standard and custom optoelectronics, including UV, visible, near-infrared (NIR), and short-wavelength infrared (SWIR) emitters, detectors, InP epi wafers, and other compound semiconductors, today reveals their new multi-chip packages combining InGaAs photodiodes and multiple SWIR LEDs in the same package. These products join a growing line of multi-chip products consisting of multi-wavelength LEDs (UV through MWIR) with or without InGaAs, silicon, or InGaAs+silicon detectors.

Our range of multi-chip products includes:

Multiple LEDs in a single package (235nm to 4300nm wavelength combinations)
Multiple detectors in a single package (multiple silicon, InGaAs, and SiC photodiodes)
Multiple LEDs + single or various detectors in a single package
Packaging options include SMD, TO-can, and our award-winning ATLAS hermetic SMD

ATLAS hermetic SMD packages are ideal for LED, detector, & multichip applications.

Co-Packaged InGaAs Photodiodes with Multiple LED Emitters

Our newest multi-SWIR LED emitters + detector components include part numbers MTMD1479PD6T38 and MTMD34679PD6T38. MTMD1479PD6T38 includes 1460nm, 1720nm, and 1900nm SWIR LED chips combined with a 2.6µm InGaAs detector providing 800nm to 2600nm responsivity. MTMD34679PD6T38 has the same 2.6µm InGaAs detector co-packaged with 1300nm, 1460nm, 1650nm, 1720nm, and 1900nm SWIR LEDs. To the best of our knowledge, our 2.6µm InGaAs detector has the highest responsivity on the market based on our internal tests and customer evaluations comparing our InGaAs detectors with our competitor’s products.

Marktech’s UV, visible, NIR, and SWIR emitters combined with our IR detectors (InGaAs photodiodes) are the perfect solution for many analytical, medical, aerospace, and industrial sensing applications. An additional silicon detector can be added to the package when UV LED light needs to be monitored or detected. The co-packaged emitters are individually addressable. Multiple chip products are available in TO can and SMD packages.

Multiple Wavelength Multi-chip Products

For applications such as transmission spectroscopy requiring a multiple-wavelength source separate from the detector, Marktech also produces multi-wavelength -devices consisting of multiple LED chips in a single package.

Our newer LED light sources, Multiple wavelength LED emitters, have several advantages over singularly packaged LEDs and older, conventional light sources. Co-packaging multiple LED emitters can:

Ability to rapidly vary light power output and wavelength
Reduce Circuitry & Simpler Design
Reduce Part Count
More compact design – ideal for wearable applications
High-speed wavelength selection
No or minimal heat dissipation – reduce heat compared to halogen, xenon, mercury vapor, or thermal IR emitters
Reduce power compared to halogen, xenon, mercury vapor, or thermal IR emitters
Increase life compared to halogen, xenon, mercury vapor, or thermal IR emitters
Fast response (on/off or pulsing) – no warm-up delay of halogen, xenon, mercury vapor, or thermal IR emitters
Elimination of moving parts – e.g., motorized slit in dispersive spectrometers
High emission stability – no or minimal wavelength drift over the lifetime

Our multiple LED and multi-detector products are available in several variations:

Multiple emitters combined with InGaAs photodiodes for Vis-NIR-SWIR detection
Multiple UVC LEDs (235nm, 255nm) with SiC photodiodes for deep UVC emission and detection
Multiple emitters joined with silicon photodiodes for UVB-Vis-NIR emission and detection
Multiple emitters sharing the same package with both InGaAs and silicon photodiodes for UVB-Vis-NIR-SWIR detection
Multiple InGaAs, silicon, and InGaAs-silicon detector combinations with different emission filters on each photodiode
Multiple InGaAs, silicon, and InGaAs-silicon detector combinations with integral transimpedance amplifiers (TIAs)
Multiple InGaAs, silicon, and InGaAs-silicon detector combinations with thermionic coolers
Multiple LED emitters of multiple wavelengths
Multiple LED emitters of the same wavelength for increased power

Multiple emitters in one package ( up to 7 in our standard thru-hole or SMT package) along with detectors in a separate package (4, 5, & 6) can be helpful in colorimeter and color photometer applications using cuvettes where the excitation light is transmitted through the sample – or, where the excitation wavelength(s) needs to separate from the photodiode detector(s).

The specific combinations of emitters and detectors can be tailored or “mixed and matched” to your application’s specific light source and detection requirements.

In applications requiring higher power, multiple LED die of the same wavelength are placed in the same package. For example, Marktech’s MTMD4270T38 product contains two 428nm LEDs and two 700nm LEDs. Our MTMS1300N24 SWIR LED emitter contains three 1300nm chips in a narrow domed lens TO-can package. Our MTMD7885T38 multiple wavelength emitter has three 770nm die in a PLCC package. Our MTMS7700T38 (770nm), MTMS8800T38 (880nm), and MTMS9400T38 (950nm) products utilize six LED emitter chips in the TO-can package.

Examples of Marktech’s multiple wavelength, multi-chip LED products

InGaAs detectors and InGaAs photodiodes with multiple LEDs are beneficial in a variety of applications, such as:

Biomedical instrumentation
Black ice detection
Broadband, hyperspectral, and multispectral light sources
Colorimetry
Contamination or foreign material detection
Counterfeit currency detection
Curing / Crosslinking
Endoscopic lighting and tissue oximetry
Fluorometry
Fluorescence microscopy
Functional near-infrared spectroscopy (fNIRS)
FURA / calcium imaging
Glucose monitoring
Industrial machine vision
Iris matching or recognition for biometrics
NIR spectrometry
Optical communications
Optogenetics
Oximetry / Co-oximetry
Photodynamic therapy
Photometry
Solar simulation
Sorting equipment
Spectroscopy
SWIR Detection
SWIR Imaging

In some applications, the integral detector acts as a monitor to indicate the LEDs are emitting light. In other cases, the InGaAs can detect reflected or fluorescence emission from a sample illuminated by the LEDs. For example, oximeters, NDIR, and fNIR devices can emit and detect the reflected or partially transmitted light to determine oxygen levels in the tissue. For applications that require light transmitted through a sample and then detected, Marktech can package the LEDs and InGaAs detectors separately.

In dispersive spectroscopic analysis, a monochromator generates a wide range of wavelengths. Monochromators employ a prism or diffraction grating combined with a motorized slit to select a specific excitation wavelength. Typically, we look at the peaks of an unknown chemical or material analyte and compare them to libraries of identified reference spectra.

In specific applications with unknown amounts of known analytes in a closed system, only a few specific wavelengths are required to distinguish between and quantify particular chemical constituents. Examples of applications where a selection of specific wavelengths is helpful in chemical analyte quantification include:

Spectroscopically analyzing the amount of reactant in a chemical production process
Colorimetric analysis of process, drinking, or wastewater contaminants
Oximetry, optical glucose monitoring, ischemia detection, and other medical diagnostics
Fluorometry for fluorescence identification of minerals or biological materials
Fluorescence microscopy for life science imaging (cells, proteins, biological materials)
Non-dispersive infrared (NDIR) spectroscopy-based gas analyzers or gas sensors

In one of these “closed systems” with multiple analytes, sometimes the more efficient option is not to choose wavelengths corresponding to the peaks of the analytes but rather a few wavelengths producing the most significant differences between the analyte’s absorption, reflectance, transmission, or fluorescence. With this methodology, fewer LED emitters can often provide better analytical results. In addition, the ratio transmission results from two or more wavelengths can account for slight interference in turbid or dirty samples.

Multiple LEDs in Spectrometry, Fluorimetry & Fluorescent Microscopy

Eliminating the monochromator combined with LED emitters’ higher natural monochromatic nature can produce a higher power excitation light source than a dispersion spectrometer with broadband xenon, halogen, and mercury sources. In dispersion spectrometers, conventional light sources are broken into 128 or 256 wavelengths, with each wavelength having only a fraction of the energy of the source. Higher-power LEDs at specific peak wavelengths can improve the signal-to-noise ratio.

When comparing or discerning two analytes, specific wavelengths provide no additional information when the absorption levels of the two species are equivalent. Therefore, eliminating these wavelengths and using a few critical discerning wavelengths can speed up the overall detection process.

In addition, since a handful of the target excitation wavelengths are picked, each wavelength source can be optimized for high power output and increased wavelength monochromaticity. For instance, additional LEDs with the same wavelength can be packaged in the same TO can, PLCC, or SMD package to provide higher power for a particular wavelength. In addition, Marktech can sort or bin LED emitters to produce tuned LEDs with minimal peak wavelength variation of ±1nm. In higher-volume applications, wavelength variation and power output can be adjusted at the wafer level or in the light-emitting diode fabrication process. Likewise, InGaAs and silicon detectors can be customized during semiconductor fabrication to specific sensitivity ranges – when production volumes warrant the development.

Fluorometers (fluorescence spectrometers) and microscopes utilize a specific excitation wavelength capable of exciting a fluorescent dye or fluorophore in a sample, emitting at a peak emission wavelength. Cells, tissues, and other biological samples are often examined with fluorescence. LEDs eliminate several problems in fluorescence studies compared to older light sources, such as overexposure to light, thermal damage and phototoxicity of the biological sample, and photobleaching of fluorescent dyes or proteins. The peak wavelength of the LEDs can be selected to match the excitation wavelengths of the fluorophores closely. Combined with the higher intensity or power output at the peak wavelength, the result is improved signal-to-noise in fluorometry and fluorescence microscopy applications. Our multi-wavelength LED packages enable the selection of a different excitation wavelength for different fluorophores, fluorescent dyes, or color-indicating reagents. For instance, our MTMD2336T38 multi-wavelength light source can selectively emit 275nm, 310nm, 360nm, and 380nm wavelengths, and our MTMD3334T38 multi-wavelength light source can selectively emit 310nm, 360nm, 380nm, and 430nm wavelengths.

NIR and incredibly SWIR wavelength light can penetrate deeper into human tissue than visible light due to the reduced photon scattering at these wavelengths. SWIR’s high penetration depth enables imaging and spectral information collection deep into tissues. Some of these NIR/SWIR infrared imaging systems have mapped blood flow in live animals and imaged tissue 5mm into mouse brains. In addition, infrared spectroscopy can provide information on deep tissue chemical composition, such as oxygenation and deoxygenation. In the article, “Shortwave infrared fluorescence imaging with the clinically approved near-infrared dye indocyanine green,” the researchers stated that “imaging in the shortwave IR (SWIR; 1,000–2,000 nm) promises higher contrast, sensitivity, and penetration depths compared with conventional visible and near-IR (NIR) fluorescence imaging.” The researchers used NIR and SWIR light sources with an InGaAs detector. Marktech has many singular and multi-wavelength LED emitters in the NIR and SWIR wavelength ranges. For example, the Marktech MTMD142345PDT38 multiple SWIR wavelength emitter-detector contains 1040nm, 1200nm, 1300nm, 1460nm, and 1550nm peak wavelength LEDs combined with our InGaAs photodiode for SWIR detection in the 600nm – 1750nm range. These SWIR emitter-detectors can be helpful in tissue oxygenation and utilization studies using NIRS methods.

In summary, spectrometry, fluorescence microscopy, and other optical analytical methods performed with a specific set of multiple LED light sources and the appropriate photodiode detector can have improved signal-to-noise ratio and detection speed.

Maximize Your Total Cost Benefit with Tailored Photodiodes and LEDs for OEM Designs

Photodiodes and LEDs are widely used in a range of applications, including optical sensors, communication systems, medical diagnostic devices, analytical instruments, and application specific lighting. They are often used together to maximize the total cost benefit, with photodiodes serving as detectors and LEDs as emitters. By tailoring these components to OEM design needs, engineers can optimize performance while minimizing costs.

Photodiodes are semiconductor devices that convert light into an electrical current. They are commonly used in applications such as light detection and communication systems, where they can be used to detect changes in light intensity or to transmit data via optical signals. Photodiodes can be designed with different materials and structures, such as silicon, SiC, or InGaAs, to optimize their sensitivity and response time for specific applications.

LEDs, on the other hand, are semiconductor devices that emit light when a voltage is applied to them. They are commonly used as light sources in a range of applications, including displays, lighting, and communication systems. LEDs can also be designed with different materials and structures, such as GaN or InGaN, to optimize their emission wavelength and brightness for specific applications.

By combining photodiodes and LEDs together in the same package, engineers can create efficient and cost-effective systems. For example, in a communication system, an LED can be used to transmit data via optical signals, while a photodiode can be used to receive the signals and convert them back into electrical signals. By selecting the appropriate photodiode and LED components for the system, engineers can optimize the performance and cost of the system.

What is total cost benefit?

“Total cost benefit” refers to a comprehensive evaluation of both the financial and non-financial gains that can be derived from an investment, action, or decision, in relation to the total costs involved, including financial expenditures and potential risks. This approach does not just look at the monetary aspect but also considers other benefits such as improved safety, convenience, or time savings, while accounting for all associated costs including potential downstream or auxiliary costs.
To obtain a true sense of the total cost benefit, one needs to examine all potential gains and savings, direct and indirect, tangible and intangible, that may result from the decision, and then compare it against a fully loaded cost profile that encompasses every possible cost, direct and indirect, associated with that decision.
A total cost benefit analysis aims to provide a more rounded view of the value proposition of a decision by exploring it from multiple dimensions, and it is a critical tool in both business and policy making, aiding stakeholders in making informed decisions grounded on a holistic understanding of the potential outcomes. It offers a macro perspective, enabling a thorough evaluation and thereby facilitating choices that are aligned with long-term objectives and holistic wellbeing.

Maximizing Total Cost Benefit with Customization

To maximize the total cost benefit of photodiodes and LEDs, engineers should carefully consider the specific needs of their OEM designs. This includes selecting components that are optimized for the specific application, as well as components that are cost-effective and reliable. It also involves selecting components that are easy to integrate into the overall system design, with minimal additional components required.

For example, in a sensing system, the photodiode and LED components should be selected based on the desired sensitivity and wavelength range of the system. The components should also be selected based on their reliability and cost, with consideration given to the overall cost of the system. Additionally, the components should be designed with ease of integration in mind, to reduce the overall system complexity and cost. Standard or lower cost optoelectronic components often do not minimize the total system cost of a design or the “total cost of ownership”. For example, a design engineer may have planned on buying two separate photodiodes to meet the detection wavelength range requirements of the project. Marktech’s custom solution combined two photodiodes in the same package resulting in a lower total cost and less complicated design compared to purchasing two separate detectors.

In some cases, a detector has more gain than is required for a project. For these optoelectrical design projects, Marktech has custom developed lower active area detectors, which are less costly than a standard photodiodes with larger active areas.

Bacteria or microbes can have sensitivity to destruction at certain wavelengths. For instance, cryptosporidium is sensitive to or most effectively killed by 265nm light. In some sanitization cryptosporidium applications, mercury vapor lamps with a wide spectrum are used. Power is wasted because some of the wavelengths emitted are ineffective at destroying the bacteria Marktech can provide 265nm LEDs specifically targeting cryptosporidium eliminating providing a design with more energy efficiency and longer battery life. Likewise, Marktech can provide 235nm and 255nm deep UVC wavelengths for the detection of creatine, uric acid, proteins, nitrates in water or blood samples.

In addition, off-the-shelf parts frequently cannot provide the optimized performance of a bespoke detector or LED developed specifically for a new electro-optical product design. Even if the overall cost of the system is slightly higher using a custom part than a standard component, the performance per cost is higher or the total cost benefit is lower.

An intangible benefit is the competitive advantage provide provided by unique, custom LEDs or photodiodes. Bespoke optoelectronic parts can provide unique optoelectrical characteristic unlike any catalog type components. A design with a standard component can be more easily reversed engineered and then duplicated. Custom LEDs or custom detectors cannot be duplicated as easily or at all in some cases.

Tailoring LEDs and photodiodes to the specific design requirement can eliminate the need for additional component such as optical filters, amplifiers, lenses, etc. – resulting in lower system cost, higher product performance, or higher total cost benefit.

(www.marktechopto.com)(Marktech), a privately-held leading designer and manufacturer of standard and custom optoelectronics, including UV, visible, near-infrared (NIR), and short-wavelength infrared (SWIR) emitters, detectors, InP epi wafers, and other compound semiconductors, today announced the release of their enhanced sharpness 25 and 50 micron green dot point source LEDs (MTSP-1358 and MTSP-1360) for reflex sights, riflescopes, sports optics, camera viewfinders, and other aiming applications. In addition, Marktech expanded their offering of red dot LEDs with additional micron sizes and package types.

Our green dot LEDs utilize a “true green” 520nm wavelength, which appears brighter to the human eye compared to a 650nm red point source with equivalent power output. Green dots appear “brighter” because the rod receptors in the human eye have the more response to 520nm green light than 650 red light. However, red dots are still desirable in many applications. For instance, if the background, foliage, or target is a similar shade of green, then a red dot might be a better option.

Standard red dot LEDs micron sizes include 25 µm, 50 µm, 80µm, 100 µm, and 150 µm. Red dot LEDs with micron sizes of 10µm, 13µm, 30µm, 40µm, and 60µm available on a custom basis. Our standard red dot LEDs are available in two package types: a 2.1×2.1 SMD Flat Lens and a 1.6×1.5 SMD Flat Lens. Several additional package type options are available such as chip on board (COB) and flex circuit. Marktech can also custom design package for OEM needs.

Marktech’s 2.1mm x 2.1mm package for dot or point source LEDs.

Marktech’s red dot-circle-cross reticle LED with individually addressable elements.

Marktech can assemble the red dot or reticle die into various standard and custom packages as well as chip-on-board (COB), rigid PCB, and flexible circuit assemblies. We have also incorporated our avalanche photodiode (APD) detectors in conjunction with red dot and display reticles for riflescopes, binoculars, LIDAR speed guns, and rangefinders with laser distance, speed, or range measurement capabilities.

Red Dot LED Product Applications
The typical function of red dot and reticle LEDs is aiming or targeting. The red dot appears within the riflescope or reflex sight. The reflected image of the red dot LED on the optical lens provides a virtual spot on the target. Unlike aiming lasers, a visible laser spot does not appear on the target, so the prey or target cannot see the spot. In addition, specialized coatings are used on the optics to enhance reflections or the red light wavelengths from the LED, which reduces the appearance of the red dot to prey, enemy combatants, or other targets.

While the recognized leader of premium red dot LEDs to the optical scopes industry, Marktech red dot and reticle LEDs find additional applications outside riflescopes and gun sights. Laser rangefinders and LIDAR speed guns often utilize a red dot aiming sight to target an object for measurement. Telescopes have a narrow field of view and require finderscopes or red dot finders to locate specific stars or constellations. An increasingly popular application of red dot LEDs is on cameras. A red dot viewfinder on a camera is helpful in the photography of fast-moving objects.
Red dot, reticle, and alphanumeric LEDs benefit a wide range of applications, including:

Riflescopes
Reflex Sights and Red Dot Sights
Illuminated Reticle Scopes
LIDAR Speed Guns
Optical pyrometers
Telescope Finderscopes or Red Dot Finders
Night Vision (NV) Devices
Rangefinders & Range-finding Binoculars
Camera Red Dot Viewfinders
Stage Lights and Spot Lights
Ocular Displays in Microscopes and Medical Optics
Displays in Smart Glasses, Goggles, and AR/VR Devices
Head-mounted display in scuba masks and helmets
Optical encoders
Edge sensors
Proprietary OEM Optical Assemblies.

Packaging Options

Marktech’s dot and reticle LEDs are available in various package types depending on the requirements of your application. For instance, our 25µm and 50µm red dot LEDs are available in both a 2.1mm x 2.1mm SMD packge and a more compact 1.6mm x 1.5mm SMD package. For applications requiring a larger package such multiple dot LEDs, reticle LEDs and microdisplay LEDs, we have 3mm x 4mm frameless SMD, COB, flex circuit, and custom designed packaging options.

Point Source LEDs

Our small 10 µm diameter red dot LEDs and visible or NIR point source LEDs can replace lasers in specific applications. They are also used as emitters in optical encoders, position sensors, edge sensors, light barriers, and other sensing applications. For sensing applications requiring higher power visible or infrared (IR) emission, Marktech has a series of point source LED emitters from the 620nm to 650nm in the visible band and from 750nm to 980nm in NIR band.

Buying Your Engineer or Scientist a New Photodiode for Christmas? 8 Questions to Ask When Selecting A Photodetector Manufacturer

Marktech’s innovative hybrid and silicon-InGaAs detectors.
Si-InGaAs photodiodes can enable broadband detection from 254nm to 2600nm

1. How extensive is the photodiode manufacturer’s product offering? Do their photodiodes have the wavelength sensitivity, speed, active area, and other performance parameters to meet your photo- detection requirements?

The supplier should have a broad enough product line to meet your current and future needs.

They should have photodiodes in their line-up meeting your application’s wavelength sensitivity, speed, dark current, and size needs. For example, Marktech produces both silicon and indium gallium arsenide (InGaAs) photodiodes, which provide a wavelength sensitivity range from 250nm to 2600nm – or, over the ultraviolet (UVB), visible, near infrared (NIR) and short wave infrared (SWIR) bands. Marktech has an extensive line-up of photodiode detectors with these wavelengths with a range of active areas and package types. However, suppose the supplier only has one or few types of photodiodes. In that case, photodetectors may not be their main focus. As a result, they will not be able to provide as many choices, assistance in selecting the suitable detector, and guidance in developing detector specifications.

Marktech has 500+ standard or catalog detectors, LED products, and over 3000 customized products. Most catalog products are available immediately through our distributors, Digi-Key Electronics and Mouser Electronics.

In 2021, Marktech products became available in Japan through our latest partner, Rikei Corporation. Established 65 years ago in Tokyo, Rikei Corporation is a trusted trading partner and value-added solutions provider serving many electronic original equipment manufacturers (OEMs) and communications companies. Rikei excels in system integration and component distribution, leveraging superior procurement skills, deep domain knowledge, and expertise in systems technology and electronics for high-quality solutions throughout the project lifecycle.

Marktech also has sales engineering representatives in Canada (ARL Group), Israel (Militram), and France & Germany (Syscom-Prorep). Our extensive offering and ability to tailor products to specific OEM design specifications have long set Marktech apart from other optoelectronic manufacturers. For example, Marktech’s photodiode detectors have various wavelength sensitivity ranges, active area sizes, and package types including TO can, SMD, PLCC, through-hole, and hermetic SMD packaging.

2. Are they familiar with specifying photodiodes for your industry application? Can the manufacturer modify or customize their photodiodes to suit your needs?

Custom 64 element Si PDA for ice particle measurements on aircraft wingtip.

The supplier should be familiar with your application or ideally developed or customized photodetectors for similar use cases. Every application can have unique details necessitating intricate modifications to detector specifications to enable viable detection levels. Off-the-shelf or catalog photodiodes can be sufficient for less demanding applications. However, we have found in many cases that customization of a photodiode in terms of wavelength sensitivity, active area size, package type, and hermetic properties can increase the overall performance and reduce the total cost of your design. The custom component cost might be slightly higher, but reducing part count and simplifying circuit designs can result in a total cost benefit. In addition, Marktech can further customize photodetector designs by adding amplifiers, thermionic coolers, and LED emitter in the same package. Marktech can also apply anti-reflective coatings and filter coatings to windows or lids. Marktech has partnered with many OEMs to develop specialized InGaAs and silicon photodiode detectors for aerospace, analytical instrument, automotive, automation & industrial sensing, medical, and wearable applications. Our products can be found on satellites, top-tier automobiles, non-invasive medical diagnostic devices, position sensors, spectrometers, refractometers, laser alignment systems, and colorimeters.

3. Does the supplier produce LED emitters with your application’s wavelength, power output, and package type?

Position sensing, spectrometry, refractometry, LiDAR, security, and other industrial applications often use photodetectors in conjunction with an LED emitter or light source. Therefore, the manufacturer should have LED emitters with the wavelength and power ranges to complement the photodetector selected. Marktech has an extensive line of LED emitters to provide the proper light source for InGaAs and silicon photodiode detectors selected. Marktech’s testing laboratories can evaluate both emitters and detectors. In addition, our labs can customize or sort LEDs to tighter or lower variations in peak wavelength (±1nm). Our optoelectronics engineers and LED experts can further customize LEDs with packaging and assembly options such as flex circuits, COB, and PCB.

4. How long has the photodiode manufacturer been in business under the same ownership? Are they increasing in size, facilities, and capabilities?

The photodiode manufacturer should be a stable business. If the manufacturer has changed hands through acquisitions or bankruptcies, closed factories, or cut many detector product offerings, then the supplier may not be the best supplier. Instead, look for an established supplier with stability and expanding product offerings, capabilities, manufacturing plants and testing laboratories. Marktech was founded in 1985 by Mark Campito, a Navy veteran, who is still the CEO. Marktech has continuously focused on testing and invested significantly in creating world-class optoelectronic testing laboratories capable of analyzing photodiode detectors and LEDs. Marktech’s philosophy is that optoelectronics testing is crucial in maintaining product quality and consistency. In 2021-22, Marktech upgraded our detector and LED testing facilities in Latham, NY. Marktech also installed extensive burn-in test capabilities for component and assembly evaluations. In 2014, Marktech built and opened a new state-of-art silicon photodiode manufacturing plant in Simi Valley, California. Marktech Optoelectronics has continuously operated in New York State since 1985.

5. Does the supplier have a history of innovation, quality, and reliability? How often are new products added to their line-up?

Cutting-edge optoelectronic design require a supplier with innovative product and a willingness to customize and try new approaches, and expand the capabilities of their photodiode when required by a customer’s application. The frequent additions of new products to a photodiode manufacturer’s catalog indicates growth and innovation. Marktech is constantly adding new and innovative product to their portfolio of photodetectors and LED emitters. In addition, Marktech’s photodiode detectors are recognized and sought after for their integrity and reliability. In 2023, Marktech’s ATLAS Hermetic SMD Packaged InGaAs Photodiodes won the Best of Sensor award in the Aerospace/Space category at the Sensors Converge conference and exhibition. The award demonstrates Marktech’s ability to develop and manufacture high performance photonics products. Marktech’s award winning, compact hermetic SMD ATLAS packaged InGaAs photodiode (right) compared to a bulky TO can packaged detector (left).

6. Is the photodiode supplier an integrated optoelectronics manufacturer?

Ideally, the photodiode supplier you select will be “integrated” or manufacture the photodiodes device at the wafer level, dice the wafers into photodiode chips, package the chips, and when required assemble onto printed circuit boards (PCB, COB, flex circuits). Manufacturing integration provides more control of the quality and consistency because a single company oversees every step of the photodiode manufacturing process. There is no finger-pointing between suppliers, and any quality issues are quickly identified and resolved. New photodiode detectors are rapidly developed and delivered as well. Marktech is an integrated InGaAs photodiodes manufacturer. Our InGaAs photodiodes are fabricated on our Custom Designed MOCVD chambers in Japan. The InGaAs detector die are packaged, assembled, and tested in the same facility. Our Japanese factory has extensive optoelectronic engineering and photodiode design expertise.

Our InGaAs photodiode detector factory in Japan

7. Can the manufacturer fully test the characteristics of photodiodes and LEDs? What type of testing facilities does the manufacturer have for evaluating photodiodes and LED emitters?

The ability to test is essential in assuring quality, troubleshooting application problems, and simulating field conditions. In some cases, testing can show how variations in the application or use of a photodiode causes detection issues, which can be resolved through packaging, end-product design changes, or photodiode chip specification adjustments. Marktech has extensive expertise and laboratories for optoelectronic testing of both detectors and LED emitters.

8. Will the manufacturer be able to deliver in time to meet your design project schedule? Does the supplier have catalog or standard photodiodes available through major distributors? Where are their photodiode manufacturing facilities located?

Photodiodes should be manufactured in a country without supply chain issues arising from COIVD shutdowns, political upheavals, sanctions, or transportation problems. Ideally, your photodiode supplier should be located near your factory or within the same country. If the manufacturer has a catalog or standard offering of photodiodes, then these products could be delivered rapidly. In addition, while the specific photodiode might have to be customized for your application, a standard photodiode might help move the development process forward and collect data to finalize the photodiode specification.

Marktech has manufacturing facilities in Simi Valley, California and in Japan. We have extensive optoelectronic engineering and testing laboratories in Latham, New York and in Japan. Marktech has one the shortest delivery lead times in the photodetector industry for standard and custom photodiodes. Marktech’s standard photodiodes are available through Digi-Key Electronics and Mouser Electronics, so there is still time to order a new photodiode optical sensor for your special person.

This state-of-the-art photodiode meets the advanced needs of applications such as beam centering, beam nulling, position centering, beam alignment, optical tweezers, atomic force microscopes (AFMs), fine sun sensors (FSSs), and free space optical receivers.

Marktech's new New 50mm2 Active Area Si Quadrant Photodiode MT03-072 — New 50mm2 Active Area Si Quadrant Photodiode MT03-072

The MT03-072 stands out in the market with its unique packaging in a hermetic TO-8 metal can. This robust packaging is expertly engineered to protect the photodiode and maintain optimal performance even in the most challenging environments. It effectively prevents the ingress of oxygen, moisture, water vapor, and other corrosive gases known to degrade semiconductor materials. These attributes make the MT03-072 exceptionally reliable and durable compared to products in standard plastic SMD or non-airtight packages.

One of the remarkable features of the MT03-072 is its non-outgassing nature in vacuum, low-pressure process chambers, or space environments due to its all-metal package containing no plastic or volatile organic compounds. This characteristic is crucial for high-precision applications where outgassing can significantly affect performance and results or damage the detector.

The MT03-072 quadrant photodiode or photodetector are made using Marktech’s proprietary Series 8 SiPD process offering a responsivity range from 350nm to 1100nm, with a peak sensitivity around 940nm to 980nm. This broad range ensures that it caters to a wide spectrum of applications, delivering high detection efficiency coupled with low noise.

For example, near infrared (NIR) laser beams with wavelengths of 800 to 980nm, 940nm, and 1064nm are commonly utilized for optical tweezing biological materials like cells, bacteria, or spores. NIR light provide a good balance between minimizing photodamage, low interference with fluorescence imaging excitation, and producing effective trapping forces. Atomic force microscopes are used to manipulate cells as well as measure surfaces at the atomic and nanoscale. These instruments utilize NIR lasers and quadrant photodiodes for precise position measurement of their cantilever or probe deflections. Marktech quad PDs are ideal for optical tweezer and atomic force microscope (AFM) applications.

Quadrant photodiodes are also used as optical receivers in free-space optical communications systems. A laser beam transmits a signal to a quadrant receiver using visible, NIR, or SWIR wavelengths. Water vapor, carbon dioxide, and other gases absorb light at specific wavelength ranges. Optical transmission bands occur between these regions of high absorption. Typical NIR laser wavelengths for free space communications include 808nm and 1064nm (Nd: YAG lasers), well within the MT03-072 photodiode specifications.
