Utilizing our 30 years of experience in optoelectronics, Marktech’s customization process focuses on customer needs and applications. Instead of using standardized–but perhaps non-optimized–parts, Marktech allows advantageous custom product variations to enhance your product design.

Custom packaging and electrical sorting of products offer further differentiation. Marktech provides the designer with insights concerning custom variations–variations that optimize electrical, optical, and thermal characteristics–without the need for large volume commitments. With manufacturing facilities in California, Germany, and Japan, Marktech is a vertically-integrated company, allowing us to produce detector components quickly, thus decreasing your time to market. We can even produce your entire package in the United States, if need be.

To solve your needs, Marktech engineers will discuss with you:

  • Application needs specific to your project
  • Optimization recommendations for component and assembly packaging, technology, and thermal and electrical parameters
  • Manufacturing of dedicated end-products in support of your specifications and needs

In this second installment in our six-part series on Marktech’s customization capabilities, we focus on optoelectronic detector materials, to allow options to customize detector components for optimal mating with compatible emitters.

Overview

Photodetectors are sensors, detecting light and converting the photons into measurable currents, and are therefore useful for applications ranging from water faucets to nuclear transient events. With varied technologies and packaging, specific measurements can be made that are ideal for your applications.

Marktech devices are solely solid-state devices (there are no photomultiplier tubes in our product line, although our products may supply similar functionality). Response rates can be as fast as 300 picoseconds. Light levels that can be measured range from tens of photons to massive levels. Wavelengths can range from 150nm to greater than 3000nm.

Each photo­­detector uses a p-n junction as part of either a photodiode or phototransistor construction, effectively working as an inverse function from the typical operation of a light emitting diode. Depending on the technology used, the detectors provide current response to specific ranges of light wavelength.

Detector Materials and Characteristics: The materials used may be silicon, GaP, or InGaAs. The P and N epitaxial layers of the wafer materials can be optimized for specific customer specifications and desired characteristics, including minimum reflection, Optimized Responsivity, low dark current, minimum series resistance, low capacitance, fast response, low cross talk, and more. The detectors can be packaged in a variety of packages from metal can and standard 3mm and 5mm plastic packages, to surface-mount…or virtually any custom package assembly. Detector applications range from simple door opening to the latest cancer PET scan system.

Detector Wavelengths: Available products have wavelengths varying from 150nm (UV) through the visible range (440 to 700nm), through SWIR (short wavelength infrared) (up to 2600nm), and beyond to MWIR (medium wavelength IR) (>3000nm). This link to our online Product Selector Guide helps in the selection of the emitter wavelengths, while also indicating compatible detectors. Tight binning by Marktech can provide uniform wavelength characteristics to optimize the application and mating detectors’ sensitivities, providing process-controlled, uniform product solutions.

Marktech Photodetector Variations:

  • Silicon photodetectors (400nm to 1100nm): photovoltaic, photoconductive photodiodes, and phototransistors
  • Silicon avalanche photodiodes (400nm to 1100nm, with 800nm, 905nm optimization)
  • UV detectors (150nm to 450nm)
  • InGaAs PIN photodetectors (800nm to 2600nm) and SWIR (short wavelength IR) detectors (1050nm to 1720nm)

Products are also available in epitaxial wafer form, and can be packaged as photoreflectors, arrays, and hybrid parts. For part listing and additional information, visit https://marktechopto.com/marktech-detectors.cfm

Silicon Photodetectors (400nm to 1100nm): Marktech’s silicon phototransistors can be utilized in applications requiring very high sensitivity, uniform response, and increased reliability such as card readers and optical sensors.

The photovoltaic silicon photodetectors have a spectral sensitivity from near-ultraviolet, through the visible range, to Near IR (400nm to 1100nm). These are used in applications such as medical, analytical, communications, spectroscopy equipment, and sensing requiring broadband sensitivity with enhancements in the blue/green region. These devices can exhibit moderate-speed response, high sensitivity, and low noise. Devices are available as either phototransistors or photodiodes.

The photoconductive silicon photodetectors are suitable for high-speed and high-sensitivity applications. The spectral range extends from 350nm to 1100nm, making these photodiodes ideal for visible and near-IR applications, including such AC applications as detection of pulsed LASER sources and LEDs.

Marktech’s broad line of silicon photodetectors are provided in a variety of package types including through-hole plastic, ceramic, metal-can, surface mount, and full custom. These devices are available with standard silicon die having a spectral sensitivity of approximately 400nm to 1100nm, or with special UV-enhanced silicon chips with sensitivity in the lower UV-A range. Custom active areas and multi-element chips can also be manufactured to suit your application. Many of our wafers/chips are manufactured in the USA and optimized to insure uniform and consistent performance with high reliability. These devices are well-suited for visible and near-IR applications requiring high speed and high sensitivity as well as low noise such as optical switches and optical communications.

Marktech silicon detectors can be obtained with integrated filters for reduced visible light interference or optimized for your required spectral output.

Silicon Avalanche Photodiodes (400nm to 1100nm, optimized for 800nm and 905nm):  Avalanche photodiodes are ideal for high-speed and low-light level detection in the near-infrared range. These detectors have become the semiconductor equivalent of photomultipliers in many applications including data communication, LIDAR, instrumentation, and photon counting. In addition, cost-effective customization of these APDs is offered to meet exacting design specifications. Operation voltage selection and voltage breakdown (Vbr) binning, wavelength-specific band-pass filtering, and hybridization options are among many of the application-specific solutions available at Marktech.

Marktech APDs have an internal gain mechanism, fast time response, low dark current, and high sensitivity in the near-infrared region. These APDs are recommended for applications that require high bandwidth or where internal gain is needed to overcome high pre-amp noise. In addition, Marktech APDs provide higher sensitivity than a standard photodiode and are ideal for extreme low-light level detection and short pulse detection. APDs are essentially photodetectors that provide an amplification gain stage through avalanche multiplication. They are similar to photomultipliers but are solid state semiconductor devices.

Silicon Avalanche photodiodes (Si APDs) are the preferred optical detectors for applications where the wavelength lies between 400nm and 1100nm (with 800nm and 905nm optimized sensitivities), and exhibit high speed and low noise for visible to near-IR applications. Standard versions are available in three active area diameter sizes: 200, 500, and 800um and are offered in hermetic TO cans and can also be supplied in cost-effective LCC packages.

UV Detectors (150nm to 570nm):  UV LEDs are becoming more prevalent in the industry, replacing old technology such as mercury lamps. As a result, the need for UV detection is also increasing. Marktech UV detectors are offered in a variety of TO metal can-type packages from TO-18 to TO-39 with a special UV glass lens to ensure optimum lifetime and the least amount of material degradation. Marktech offers both standard and custom packaging including components, assemblies, and bare chip options to match your application requirements

Our UV detectors use materials including GaP Schottky, GaN, and SiC. A die can be packaged individually in a variety of hermetically sealed packages or multiple die can be integrated in a custom package to suit your specific application. Marktech UV detectors offer superior stability over time and high device sensitivity with low dark current.

UV-A: Marktech also offers, on a custom basis, silicon-based UV detectors, which are designed for operation in the UV-A range. These devices are available in plastic and surface mount packages in addition to the standard TO metal can-type.

Typical industries served: Medical, industrial, scientific and analytical, environmental/ecological, and commercial

Common applications: Biomedical/chemical analysis, UV emitter output monitoring, outdoor UV sensors, gas/flame detection, spectrometers and wearable devices, emitter calibration, UV dosimetry and imaging including solar UV measurements and astronomical studies, flame sensors (fire alarm systems, missile plume detection, combustion engine control), spatial optical communications (intra- and inter-satellite secured communications), and biological and chemical sensors (ozone detection, determination of pollution levels in air, and biological agents detection)

InGaAs PIN Photodetectors (800nm to2600nm):  This high-sensitivity and high-reliability product series is ideally suited for applications in the SWIR (short wavelength infrared) wavelength range. This high-sensitivity and high-reliability product is ideally suited for optical communication devices.

Photodiode chip active area sizes from 0.1mm to 3.0mm are available to provide the optimum balance between low dark current, high speed, and light sensitivity. This allows for increased flexibility and options in a variety of applications ranging from fiber optics and high-speed optical communications to medical and chemical analysis.

Integrated TE (thermal electric) cooling is currently not utilized on our standard PIN photodiodes, thereby reducing costs and improving overall efficiency.

In addition to PIN photodiodes, Marktech offers foundry services for epitaxial growth of SWIR wafers in the 1.0um to 2.6um range, using InP material as the base substrate. Marktech is currently producing these high-reliability wafers in 2″, 3″, and 4″ diameters. Among the applications for these wafers are photodetectors, linear arrays, and image sensors. Photodetectors processed using our epitaxial wafers provide significant advantages, including lower dark current, better shunt resistance, and overall improved performance at lower operating temperatures.

Marktech manufactures InP PIN photodiodes using InGaAs/InP technology, which have a spectral sensitivity in the 800nm to 2600nm range for applications requiring low dark current, high speed, and sensitivity such as fiber optics and optical communications. Marktech’s detector die can be placed in a variety of packages from metal can TO-5, TO-18, and TO-46 to surface mount and standard 3mm and 5mm plastic packages. We can also incorporate the detector die in custom-designed assemblies.

SWIR (Short Wavelength IR) Emitters (1050nm to 1720nm): Marktech Optoelectronics is one of only a handful of manufacturers that supply emitters in the extended wavelength or SWIR range. Marktech’s standard product offering includes both through-hole and surface mount packages with wavelengths from 1050nm to 1720nm and operating currents ranging from 20mA to 350mA for high-power applications. Higher wavelength ranges up to 3000nm are available in specific package types

The SWIR wavelength range requires specialized optical detectors since standard silicon detectors have a maximum sensitivity limit of up to only approximately 1100nm. Marktech produces a line of InGaAs detectors that are optimized for sensing light in this SWIR wavelength range. These detectors can be obtained as an individual, discrete component, or they can be combined with a silicon sensor to cover the complete spectrum of light from the visible to the SWIR range. Marktech also offers the option to custom-produce multi-element devices with emitter and detector chips in the same package.

Near-IR LEDs: Light With the Power to Heal

Near-IR LEDs are increasingly being used in the medical field for everything from endoscopy to blood analysis. But a new therapeutic use of light also is emerging, thanks to research being conducted by NASA.

A “lightbulb” moment for researchers

In an attempt to put a human on Mars, NASA and other space exploration programs from around the world are pushing the envelope with the length of astronauts’ space missions. But during these long periods of time in weightlessness, astronauts commonly suffer from muscle and bone atrophy. On top of that, minor injuries do not heal as easily in microgravity.

NASA initially discovered that the LEDs being used for plant growth experiments in space also accelerated the healing process for wounds. Further research began to narrow in on the optimal wavelengths and found that when used in conjunction with hyperbaric oxygen, the best results were achieved.

The NASA scientists have discovered that near-infrared, or Near-IR LEDs in the 630nm to 880nm range are the most effective in promoting cell growth and thus stimulating faster healing. For surface healing of the skin, researchers found that the most suitable wavelength is around 660nm; for deeper wound healing, approximately 880nm appears to be most effective.

Near-IR light also shows promise for treating the muscle and bone atrophy suffered by astronauts on those long space missions. However, this emerging LED light is creating interest not only in space exploration and military applications (it’s difficult for wounds to heal in a low-oxygen/high-carbon dioxide submarine atmosphere, which lacks sunlight too), but also in civilian medical care. The research showed more rapid healing for wounds and injuries such as burns, fractures, radiation tissue damage, skin grafts, oral sores caused by chemotherapy and radiation treatments, and surgical wounds, and it even helps speed the healing of diabetic skin ulcers.

How light works to heal

Researchers believe that the Near-IR LED light therapy works by stimulating color-sensitive chemicals in the mitochondria of body tissues’ cells. Light wavelengths from 680nm to 880nm can pass through skin and muscle tissue, promoting tissue and deep wound healing. Light with higher wavelengths are able to penetrate deeper into the body. Results of clinical trials on various single- and mixed-wavelength LED lamps show that near-IR light therapy accelerates cell growth 150 to 200 percent when compared to non-treated cells.

At the Ludwig Boltzmann Institute for Experimental and Clinical Traumatology in Vienna, Austria, researchers took the initial NASA findings on the potential of near-IR and expanded them to study 470nm blue light’s impact on tissue regeneration. The Austrian researchers discovered that blue light also has a significant and positive impact on the human body’s ability to heal itself (when compared to no light therapy).

Additional research is being conducted to examine the ability of specific wavelength LED light to treat eye disorders such as lazy eye, diabetic macular degeneration, and retinopathy, and to destroy some cancer cells in conjunction with other cancer treatments. Researchers already have used red LED probes to successfully treat brain tumors. Deeply-penetrating wavelengths are being studied for treatment of cranial traumas, and potentially, to help those suffering from dementia.

Choosing the right LED options

Among the numerous benefits of Near-IR LED medical light therapy devices are the cost-effectiveness and relatively simple construction. Depending on the application, therapeutic light products may utilize LEDs with multiple wavelengths or a single wavelength and can be assembled into large, flat devices for treating a sizeable surface area, such as burns or large surgical sites.

As noted above, the light’s necessary penetration depth–depending on whether the device is for use on surface tissue or deeper muscles and bones–will determine which LED wavelength is needed. Other factors to consider are energy use and power/heat output.

Chip Choice: The Heart of Your Product

If you are developing a product that uses optoelectronic components, you know that the chip is the heart of your design. Marktech has an extensive selection of optoelectronic chips (also known as die)–ranging from deep ultraviolet (280nm) to short-wave infrared (1720nm) and everything in between, and on the detector side, from 150nm to 2600nm. But the benefits of working with Marktech extend far beyond the depth of our wavelength offerings.

Custom optoelectronic packages

Selecting the proper chip determines the effectiveness and ultimately the success of your product. With a team of experienced engineers on our staff, Marktech can help you choose the right chip(s), package materials, and configuration for your unique application. And what’s more, if needed, we can even create a completely customized optoelectronic product–interchanging virtually any die into any package configuration to meet your specific needs.

“We recently had a customer who had purchased standard parts from our distributor, Digikey,” explains Vince Forte, Marktech’s chief technology officer. “The customer tested the off-the-shelf parts and found that they worked well, however, they were not quite what was needed in their particular application. They explained ‘For our design, we need this package type, and instead of these standard wavelengths, can you substitute with these alternate chips?’ So we custom-built a package for them with different die that better-met their individual needs.”

Learn more about Marktech’s multichip packages

While other optoelectronic providers may be willing to create a custom package for large manufacturing runs, Marktech is one of the few companies in the industry that will help you create custom designs even for short-runs. In fact, our expert engineering team can help you throughout the process, from chip selection and prototyping to design; from testing to manufacturing.
In addition to our engineering and design services, Marktech also can perform tight bin selections for both electrical and optical parameters such as power output, forward voltage, and wavelength, to name a few.

New products require specific chips

Optoelectronics is a rapidly evolving field. “Although the technology behind optoelectronics isn’t new, we are still discovering revolutionary new uses for light of differing wavelengths,” notes Forte. And selecting the right chip for your application is crucial; use the wrong die and the effectiveness of your product is compromised.

For example, a multichip package that includes the wavelengths 660nm and 940nm may be used for medical equipment that measures blood oxygen levels (also known as pulse oximetry). Wavelengths of 280nm and lower can be used for disinfection. Other wavelengths can be used to test blood glucose levels without a finger prick, detect chemical substances or microbes like anthrax, improve military equipment, or diagnose a variety of diseases. Consider the ramifications if the wrong wavelength or inferior quality parts were used in each of these applications.

But it is Marktech’s newly enhanced capability to custom package these varieties of detector chips at their Simi Valley, California facility that really sets them apart from others in the optoelectronics industry.

Marktech has recently teamed with photonics industry veteran Georgios Papadopoulos to expand Marktech’s custom silicon detector design and manufacturing capabilities. Papadopoulos brings over 25 years of optoelectronics product development/design and wafer foundry process development experience.

“Our recent collaboration with Georgios is a tremendous asset to Marktech,” says Barry Jones, business unit manager over Marktech’s Simi Valley operations. “Georgios has extensive knowledge in the design and processing of all types of high-reliability radiation hard photo detectors. Teaming with him allows Marktech to offer a wide variety of high-quality customized photodetector products.”

Silicon detectors have a spectral sensitivity range of 400nm to 1100nm for applications requiring high speed, consistency, and high reliability such as optical communications, medical diagnostics, bar code readers, missile guidance, Lidar, and more.

Marktech’s detector die can be placed in a variety of packages, from metal can TO-5, TO-8, and TO-18, to surface mount COB, flex circuits, and standard 3mm and 5mm plastic packages.View Marktech’s Product Selector Guide to learn more.

In addition to their newly enhanced custom chip design capabilities, Marktech also can customize Si detector assemblies to add features such as amplification circuits (pre-amps), optical filters, and band pass filters.

“All custom design projects require very stringent quality standards,” notes Papadopoulos. “Most of the larger optoelectronics companies don’t want to deal with the rigorous specifications of custom work, especially for small to medium-size production runs. In addition to their U.S.-based manufacturing operations, Marktech has a willingness and ability to accommodate their clients’ unique needs–even for small runs–which sets them apart in this industry.”

Marktech can also build custom hybrid photodetector packages that include components like operational amplifiers and feedback circuits, in addition to the chip. “Putting these components together into a custom hybrid package means less noise, smaller size, and most important, better performance,” explains Jones. “And now that we have Georgios’ extensive photodetector chip design and development expertise as part of our design team, our capabilities are second to none.” Learn more about Marktech’s custom design and test services.
