Abstract

Abstract − An experimental system using correlated photon pairs for absolute measurements of single-photon detectors quantum efficiency has been set up at the Brazilian National Institute of Metrology (INMETRO). The establishment of this methodology is of special significance for the absolute calibration of detectors, especially for near infrared range as an alternative to the conventional radiometric methods. This paper describes the preliminary implementation of this absolute calibration method. Our first experimental results are reported and the optimization of the system is pointed out for obtaining further improvements the near future
