报道了采用可调谐移相器的平衡InGaAs/InP单光子雪崩二极管(SPAD)在正弦选通模式下工作，以降低共模噪声。这项技术能够检测到小的雪崩脉冲，这导致后脉冲减少。对于频率为20 MHz、温度为240K的激光，光子探测效率为10%的暗计数率为8.9 kHz。
We report balanced InGaAs/InP single photon avalanche diodes (SPADs) operated in sinusoidal gating mode with a tunable phase shifter to reduce common mode noise. This technique enables detection of small avalanche pulses, which results in reduced afterpulsing. For laser repletion rate of 20 MHz at 240 K, the dark count rate for photon detection efficiency of 10% is 8.9 kHz.
