| Abstract | We present a practical and easy-to-implement method for high-speed near infrared single-photon detection based on InGaAs/InP single-photon avalanche photodiodes(SPADs), combining aspects of both sine gating and self-differencing techniques. At a gating frequency of 921 MHz and temperature of-30°C we achieve a detection efficiency of 9.3%, a dark count probability of 2.8×10−6 ns−1, while the afterpulse probability is 1.6×10−4 ns−1, with a 10 ns “count-off time” setting. In principle, the maximum count rate of the SPAD can approach 100 MHz, which can significantly improve the performance for diverse applications. | |
