Argo AI which acquired Princeton Lightwave, has developed a LiDAR system based on InGaAsP Geiger mode Avalanche Photodiodes (GmAPDs) for autonomous vehicles. The GmAPDs, which operate in the SWIR (1.55 µm) spectrum and have single photon sensitivity, have a number of advantages over most LiDARs used in self driving cars which make use of near infrared (900 nm) GaAs lasers and silicon-based detectors. The most important of these advantages is the eye-safe wavelength of SWIR operation.
