Paper Abstract

Time gating for SPADs is exploited either for increasing their maximum count rate or for detecting faint signals hidden by strong unwanted light pulses. Here we describe two short-gate techniques for high-speed photon counting with InGaAs/InP SPADs: i) a sinusoidal gating system at about 1.3 GHz, with very low afterpulsing and high count rate; ii) a SiGe integrated circuit for sub-nanosecond gating with < 200 ps rising/falling edges.
