Quantum efficiency evaluation method for gated-mode single-photon detector
Akio Yoshizawa, R. Kaji, Hidemi Tsuchida · Electronics Letters · 2002
A novel method based on time-interval analysis of single-photon detection times, which makes it possible to evaluate the quantum efficiency of a gated-mode single-photon detector operating at gate frequencies such that after-pulses are involved in detection. The after-pulse probability per gate is also evaluated from the same data.
