    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.
