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)

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.

LIDAR Applications

LIDAR (light detection and ranging) is a surveying method that measures distance to a target by illuminating that target with a laser light. LIDAR uses laser light pulses, while radar uses radio waves. Avalanche photodiodes enable the LIDAR application as a remote sensing technology that optically measures properties of scattered light to find range and/or other information about a distant target.

Marktech Optoelectronics Custom Reticle Capabilities
Custom Reticle Capabilities

LATHAM, NEW YORK… Marktech Optoelectronics, a Latham, New York-based manufacturer of standard and custom optoelectronics, has announced their new custom reticle capabilities. This display technology is used in applications, which include rifle scopes, binoculars, cameras, and range finders. All of Marktech’s reticles include precise illumination for low-light environments and are highly customizable based on customer specifications.

Reticle: A series of fine lines or fibers in the eyepiece of a sighting device used as a measuring scale or an aid in locating objects.

The company has also introduced one of the first 10-micron red dot chips available on the market today. “For shorter distances, a standard 50- to 80-micron red dot is probably fine,” explains Vincent Forte, Marktech’s chief technology officer, “but for longer distances, a 10-micron red dot is preferred; the smaller the dot, the more accurate the device.”

Marktech can design and manufacture a red dot and/or reticle in nearly any shape, size, or configuration, and this unique customization capability gives them an advantage in the industry. “We have the ability to create a reticle and/or red dot in conjunction with a 7-segment numeric or alphanumeric display and/or a 15 to 20-micron crosshair segment,” notes Forte. “We can assemble the die into any type of standard or custom package or chip-on-board [COB] assembly. We can even custom-design a reticle to have the segment and dot independently driven, which is quite unique in the industry.”

Devices that typically use red dots and reticles include telescopes, telescopic rifle sights, microscopes, cameras, binoculars, and other types of instrumentation. Range finders typically use a red dot and reticle in conjunction with an Avalanche photodiode (APD) as the detector, also available from Marktech. The industries most often using reticles and red dots are military, technology, recreation, or anywhere that needs a microscopic illumination source.
