论文摘要
我们调查了超导纳米线单光子探测器（SNSPDS）的定时抖动，并发现对检测器响应有很强的依赖性。通过改变多层结构，我们观察到脉冲形状的变化，这些变化归因于影响脉冲高度，上升时间和随之而来的正时抖动的电容性行为。此外，我们开发了一种技术，可以通过仅捕获单个检测器脉冲来预测单个设备的定时抖动，而当对时序抖动的粗略估计时，就消除了使用脉冲激光器进行详细的抖动测量的需求。
We investigated the timing jitter of superconducting nanowire single-photon detectors (SNSPDs) and found a strong dependence on the detector response. By varying the multi-layer structure, we observed changes in pulse shape which are attributed to capacitive behaviour affecting the pulse heights, rise times and consequently timing jitter. Moreover, we developed a technique to predict the timing jitter of a single device within certain limits by capturing only a single detector pulse, eliminating the need for detailed jitter measurement using a pulsed laser when a rough estimate of the timing jitter is sufficient.
