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.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
