Abstract

Using the correlated signal and idler photon pairs generated in a dispersion-shifted fiber by a pulsed pump, we measure the quantum efficiency of an InGaAs/InP avalanche photodiode-based single-photon detector. Since the collection efficiency of photon pairs is a key parameter to correctly deduce the quantum efficiency, we carefully characterize the collection efficiency by studying the correlation dependence of photon pairs on the spectra of pump, signal, and idler photons. This study allows us to obtain the quantum efficiency of the single-photon detector by using photon pairs with various kinds of bandwidth.
