Abstract
We report the timing response of a sinusoidal-gated Geiger mode InGaAs/InP avalanche photodiode both in synchronous mode and free-running mode. It is found that the temporal peak of photon counts is dependent on the avalanche build-up and decay times, and the break down probability is a function of the separation between the photon arrival time and the peak of the excess bias gate. We observe broadening of timing jitter and lowering the total detection efficiency in the free-running mode relative to synchronous detection.
