Ingaas absorption spectrum
Webb30 nov. 2024 · Currently, the most commonly used single-photon detectors operating in the SWIR are SNSPDs and InGaAs/InP based SPADs. SNSPDs can operate through the spectral range spanning the visible to the mid-infrared offering impressive detection efficiency, low noise, high-speed operation, as well as high count rate operation [6, 41–43].
