Statistics of Afterpulses in Silicon Single-photon Detectors under Strong Pulsed Illumination

M. V. Lakhmitski, V. N. Chizhevsky, and S. Ya. Kilin

Afterpulse statistics were experimentally studied for a number of single-photon detectors based on silicon avalanche photodiodes under intense illumination with nanosecond pulses. A significant increase in the probability of afterpulse occurrence was demonstrated for a large number of photons absorbed by the detectors. These results may be important for optimizing detector performance in quantum cryptography and for artificial pulsed neurons based on vertical-cavity lasers and single-photon avalanche photodiodes, one of whose operating modes is based on the action of sufficiently intense laser pulses.

Key words: single-photon detector, afterpulse, statistics
