We present the design and characterization of a modern near-infrared photon counting module, able to exploit the best performance of InGaAs/InP single-photon avalanche diodes for the detection of fast and faint optical signals up to 1.7 μm. Such instrument is suitable for many applications, thanks to the user-friendly interface and the fully adjustable settings of all operating parameters. We extensively characterized both the electronics and the detector, and we validated such instrument up to 133 MHz gate repetition frequency, for photon-counting and photon-timing applications, with very clean temporal response and excellent timing performance of less than 100 ps.
我们展示了一种现代近红外光子计数模块的设计与特性，该模块能够利用铟镓砷/磷化铟单光子雪崩二极管的最佳性能，用于检测高达1.7μm的快速微弱光信号。由于用户友好的界面以及所有操作参数的完全可调节设置，这种仪器适用于许多应用。我们对电子设备和探测器都进行了广泛的特性表征，并在高达133MHz的门重复频率下对该仪器进行了验证，适用于光子计数和光子定时应用，具有非常清晰的时间响应和小于100ps的出色定时性能。
