For applications where absolute numbers of photons must be measured, such as for the characterization of laser sources, the calibration of the InGaAs photodiode is very important. As the diode response of the InGaAs photodiode can vary from diode to diode, it is important that the output current levels for individual devices are calibrated.

Dr. Rebecca Ingle is a researcher in the field of ultrafast spectroscopy, where she specializes in using X-ray and optical spectroscopies to track precisely what happens during light-triggered chemical reactions.

For many applications, particularly in automation where feedback systems are used, the readout and response time of an InGaAs photodiode is very important. The new award-winning Marktech InGaAs photodiodes are also designed to have good response times for quick detection. Their key focus is very high levels of sensitivity for detection in challenging environments such as for point-of-care- medical devices or wearable technologies.

InGaAs photodiode arrays and their wide wavelength operating range are ideal for multispectral imaging and the high quantum efficiency makes them very sensitive. While normally achieving wider wavelength coverage than can be achieved in a device from an InGaAs photodiode alone is done by using multiple photodiodes, there are now developments to make single monolithic InGaAs photodiodes that integrate a GaAs layer to make a photodiode capable of detecting in the IR and visible regions.

The operating principle that underpins most photodiodes uses a P-N junction in the semiconductor material. The P-type carriers are mostly holes and the N-type carriers are electrons. Once a reverse bias is applied to the photodiode there is only a very slight movement of charge carriers through the circuit, resulting in a small level of current. For InGaAs photodiodes, the name comes from the semiconductor material that forms the P-N junction.

VIEW-IT® Ultraviolet Laser Detectors are stimulated by lasers in the ultraviolet range from 190-390 nm and emit a red-orange color at 660nm.

InGaAs photodiodes are commonly used in spectroscopy and spectrophotometry measurements and sensing. Using InGaAs photodiode arrays for machine vision and automation applications is becoming increasingly common as InGaAs photodiodes work efficiently in low visible light conditions and therefore do not require external illumination as visible cameras would.7

Some devices that require sensing over an extended wavelength range may make use of dual diodes made from different materials, such as silicon which offers better performance in the UV to the visible range.

Photodiodes only have a limited operating wavelength range. The operating range typically spans ~ 320 – 1100 nm for silicon photodiodes, so most of the visible and the near infra-red region (NIR).4 Many sensing applications benefit from using longer NIR wavelengths through to the short-wave infrared (SWIR) region.

InGaAs photodiodes use a mixture of three elements to efficiently absorb light in the ~ 800 – 2600 nm. Depending on the exact bandgap required for the sensor, the ratio of indium to gallium can be modified to achieve the right energy separation and maximize the efficiency of the InGaAs photodiode in the desired wavelength region.

Photodiodes are light-sensitive semiconductor diodes that produce a current proportional to the number of photons the diode is exposed to. Photodiodes are an incredibly important type of sensor with numerous applications, including fire safety, photovoltaics and automation.1-3 Here, we dive into the properties and applications of InGaAs photodiodes.

For medical, aerospace and more demanding applications, recent developments in the InGaAs photodiodes from Marktech Optoelectronics have shown that hermetic sealing can help improve sensor performance.8 Hermetic sealing keeps the sensors air and moisture tight so no other species can adsorb to the sensor's surface or affect the electronic properties, which could lead to inaccuracies in the current readout.

Calibration measurements are not the only important part of ensuring devices containing InGaAs photodiodes make accurate and reliable measurements. Sensors can become contaminated by their local environment, affecting the level of current readout or damaged by irradiation with intense light sources or particle collisions.

Imaging with SWIR radiation is a popular, non-destructive way of ‘seeing through’ objects to look at their contents or layers underneath surfaces. SWIR imaging has become particularly popular in art history and restoration as well as for recycling complex plastics that may be covered in labels or be a complex mixture of materials.5,6

While there is a small amount of current measured on a photodiode, even in the absence of any light, what is known as the dark current, a significant amount more charge carriers are created when light shines on the diode. The absorbed photons must be sufficiently energetic to create new charge carrier species and increase the overall current measured.

An anti-reflective (also known as anti-glare) coating prevents reflections from appearing on both the inside and outside of your eyeglass or sunglass lenses. No reflections on your lenses means more light is reaching your eyes, which inevitably improves your vision.

Successful detection of SWIR or longer wavelength region needs photodiodes made of the right material – and for these wavelength region, Indium gallium arsenide (InGaAs) photodiodes are the typical choice.
