Practical fast gate rate InGaAs/InP single-photon avalanche photodiodes

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 ${}^{\circ }$C we achieve: a detection efficiency of 9.3 %, a dark count probability of 2.8$\times 10^{-6}$ ns${}^{-1}$, while the afterpulse probability is 1.6$\times 10^{-4}$ 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.
