Abstract: We present a practical and easy-to-implement method for high-speed nearinfrared single-photon detection based on InGaAs-InP single-photon avalanchephotodiodes SPADs, combining aspects of both sine gating andself-differencing techniques. At a gating frequency of 921 MHz and temperatureof -30 $^{\circ}$C we achieve: a detection efficiency of 9.3 %, a dark countprobability of 2.8$\times10^{-6}$ ns$^{-1}$, while the afterpulse probabilityis 1.6$\times10^{-4}$ ns$^{-1}$, with a 10 ns -count-off time- setting. Inprinciple, the maximum count rate of the SPAD can approach 100 MHz, which cansignificantly improve the performance for diverse applications.
