探测器定时抖动是高级光子计数应用中的关键参数。超导纳米线单光子探测器在可见光到电信波长范围内提供最快的定时抖动，并在中红外光谱区域表现出单光子灵敏度。在这里，我们报告的时间抖动在NbTiN纳米线器件从1.56至3.5 μm波长，实现了13.2至30.3 ps的半高宽抖动。这项研究对中红外光谱区新兴的时间相关单光子计数应用具有影响。
Detector timing jitter is a key parameter in advanced photon counting applications. Superconducting nanowire single-photon detectors offer the fastest timing jitter in the visible to telecom wavelength range and have demonstrated single-photon sensitivity in the mid-infrared spectral region. Here, we report on timing jitter in a NbTiN nanowire device from 1.56 to 3.5 μm wavelength, achieving a FWHM jitter from 13.2 to 30.3 ps. This study has implications for emerging time-correlated single-photon counting applications in the mid-infrared spectral region.
