室温下高探测效率InGaAsP/InP单光子雪崩二极管
High detection efficiency InGaAsP/InP single-photon avalanche diode at room temperature
摘要
Abstract
We described a high-performance planar InGaAsP/InP single-photon avalanche diode(SPAD)with a separate absorption,grading,charge and multiplication(SAGCM)heterostructure.By electric field regulation and defects control,the SPAD operated in the gated-mode at 293 K with a photon detection efficiency(PDE)of 70%,a dark count rate(DCR)of 14.93 kHz and an after-pulse probability(APP)of 0.89%.Furthermore,when operated in the active quenching mode with a dead time of 200 ns,a PDE of 12.49%and a DCR of 72.29 kHz were achieved at room temperature.关键词
