Research Abstract

We demonstrated that InGaAs/InP avalanche photodiodes can be operated at 2 GHz gate repetition frequency. Furthermore, the high-speed single photon detector has a detection efficiency of 10% at a telecommunication wavelength (1550 nm) with a dark count probability per gate of 6 x 10^<-7>. The developed single-photon detector is suitable for the application to a practical quantum key distribution system.
