Near-infrared Single Photon Avalanche Diodes (SPADs) are the dominant, practical single photon detectors for quantum applications and low-level optical sensing. Although some infrared SPADs can ...

We extend the gate repetition rate of matched delay line transient cancellation to achieve 50 MHz photon counting with low after-pulsing and to study after-pulsing effects in InGaAs/InP Geiger-mode ...
