Paper Abstract

Current efficiency calibration of detectors need to establish primary and transfer standard, the precision will be reduced by transfer chain. We propose a scheme for efficiency calibration of infrared single photon detectors by means of twin photons.Comparing with traditional methods, the advantages of this method are mentioned. Using ultraviolet laser to pump BBO crystal, the calibration system of infrared single photon detectors based on twin photons is performed. Quantum efficiency of ID220 detector is measured as (8.71±0.02) % at wavelength of 1550nm.
