Avalanche discrimination and high-speed counting in periodically gated single-photon avalanche diodes

We discuss avalanche discrimination in a periodically-gated InGaAs/InP single-photon avalanche diode. We investigate the interrelation between the minimum detectable avalanche charge and the detection efficiency, and we show that the technical solutions we implement can improve performance. Gating the detector at 1.25 GHz, single-photon count rates above 250x106 s-1 can be obtained while maintaining low afterpulse probability with detection efficiencies larger than 0.10.
