A New Method to Investigate InGaAsP Single-Photon AvalancheDiodes Using a Digital Sampling Oscilloscope

Abstract
A near-infrared single-photon detection system is established by using pigtailed InGaAs/InP avalanche photodiodes.With a 50GHz digital sampling oscilloscope,the function and process of gated-mode (Geiger-mode) single-photon detection are intuitionally demonstrated for the first time.The performance of the detector as a gated-mode single-photon counter at wavelengths of 1310 and 1550nm is investigated.At the operation temperature of 203K,a quantum efficiency of 52% with a dark count probability per gate of 2.4E-3,and a gate pulse repetition rate of 50kHz are obtained at 1550nm.The corresponding parameters are 43%,8.5E-3,and 200kHz at 238K. -
