Abstract
We demonstrated calibration on the detection efficiency of Si-avalanche photodiode (APD) and InGaAs-APD singlephoton detectors by correlated photon pairs at 780 nm and 1550 nm, respectively. The correlated photons were generated by spontaneous frequency down-conversion in a periodically poled potassium titanyl phosphate crystal (PPKTP) pumped by a pulsed fiber laser. The uncertainty of ~10-4 on detection efficiency was obtained for both single-photon detectors.
