Detection efficiency characteristics of free-running In Ga A

发布时间：2024-05-10 05:27

　　In Ga As/In P avalanche photodiodes(APD) are rarely used in a free-running regime for near-infrared single photon detection. In order to overcome the detrimental afterpulsing, we demonstrate a passive quenching active reset integrated circuit. Taking advantage of the inherent fast passive quenching process and active reset to reduce reset time, the integrated circuit is useful for reducing afterpulses and is also area-efficient. We investigate the free-running single photon detector’s afterpulsi...
