抖动是超导纳米线单光子探测器（SNSPD）的关键参数之一。使用优化的时间相关单光子计数系统进行抖动测量，我们广泛研究了系统抖动对偏置电流和工作温度的依赖性。单光子响应脉冲的信噪比被证明是系统抖动的一个重要因素。通过使用高临界电流 SNSPD，最终系统抖动降低至 18 ps，其固有 SNSPD 抖动为 15 ps。使用 15 ps SNSPD 的激光测距实验在 1550 nm 波长下实现了 3 mm 的记录深度分辨率。 (C) 2013 年作者。除非另有说明，所有文章内容均根据 Creative Commons Attribution 3.0 Unported License 获得许可。
Jitter is one of the key parameters for a superconducting nanowire single photon detector (SNSPD). Using an optimized time-correlated single photon counting system for jitter measurement, we extensively studied the dependence of system jitter on the bias current and working temperature. The signal-to-noise ratio of the single-photon-response pulse was proven to be an important factor in system jitter. The final system jitter was reduced to 18 ps by using a high-critical-current SNSPD, which showed an intrinsic SNSPD jitter of 15 ps. A laser ranging experiment using a 15-ps SNSPD achieved a record depth resolution of 3 mm at a wavelength of 1550 nm. (C) 2013 Author(s).
