INGAAS Photodiodes for the LiDAR Technology of the Future

Highest quantum efficiency at 2 μm

In a study exploring new possibilities in short wave infrared (SWIR) sensor technology, scientists at the University of Western Australia found that LASER COMPONENTS’ IG22 series InGaAs photodiodes offer the highest quantum efficiency at 2 µm. For this study, they compared data from sensors made by several leading manufacturers.

The wavelength range explored is particularly interesting because LiDAR and similar optical tracking techniques achieve their highest range at 2 µm. The influences of scattering and refraction balance each other. In contrast to shorter wavelengths, pulsed lasers in the SWIR are considered eye-safe; thus, it is possible to achieve higher pulse energies. In addition, the systems are less susceptible to interference such as fog, dust, or smoke. Experts, therefore, believe that technologies for civil and military tracking systems will soon shift to this wavelength range (e.g., when it comes to sensors for autonomous driving).
