Abstract
We have investigated the performance of an InGaAs/InP avalanche photodiode for photon counting at 1550 nm in the temperature range of thermoelectric cooling. A quantum efficiency of 13.7% was obtained at , while the dark-count probability per gate was kept as small as . The developed single-photon detector would yield a 104.4-km fiber-optic quantum key distribution in the ideal condition.
