摘要
Spike noise cancellation is important for high-speed single photon avalanche photodiode. In this article, we demonstrated a balanced single photon detector at 1.5 m that contains one InGaAs/InP single photon avalanche photodiode and one matched variode. Suppression ratio of 27 dB can be achieved. At 253 K, detection efficiency of 13.9% is obtained with 1.06 x 10(-5) per gate dark count probability and 4.3% after-pulse probability at 100 MHz gating frequency.
