InGaAs Single-Photon Avalanche Diodes (SPADs)


InGaAs avalanche photodiode (APD) is a special device for short wave near-infrared single photon detection. It can meet the technical requirements for high-efficiency and low-noise single photon detection in the fields of quantum communication and weak light detection, and realize the detection of 0.9 ~ 1.7 μ m wavelength single photon detection.
