Abstract

We report a telecom-band single-photon detector for high-speed quantum key distribution systems. The single-photon detector is based on a sinusoidally gated InGaAs/InP avalanche photodiode. The gate repetition frequency of the single-photon detector reached 2 GHz. A quantum efficiency of 10.5 % at 1550 nm was obtained with a dark count probability per gate of 6.1×10 and an afterpulsing probability of 3.4 %.

Keywords: Single-photon detector sinusoidal gate operation telecomm-band
