    Abstract

    The measurement facility based on parametric down-conversion technique was established to measure the quantum efficiency of the near-infrared band single-photon detector. The correlated photons were generated via spontaneous parametric down-conversion in a periodically poled potassium titanyl phosphate crystal pumped by a 518 nm picosecond laser. The detection efficiency of Si-avalanche photodiode and InGaAs-avalanche photodiode single-photon detectors were measured via correlated photon pairs at 778 nm and 1 550 nm, respectively, and the measrement uncertainty was analyzed. The experiment results indicated that the facility can measuer near inferad single-photon detectors quantum efficiency with 1% measrement uncertainty.
