THE EFFECT OF AFTERPULSES PHENOMENA ON NOISE FACTOR OF AVALANCHE PHOTODETECTOR OPERATING IN PHOTON COUNTING MODE
The expressions for determination of the noise factor for avalanche photodetector operating in photon counting mode are proposed. This expressions include the effect of afterpulses and dead time of photodetector. The silicon avalanche photodetectors noise factor depending on the supply voltage, ambient temperature, the power of registered optical radiation are measured.
