Abstract

We developed superconducting nanowire single-photon detectors based on tungsten silicide, which show saturated internal detection efficiency up to a wavelength of 10 μm. These detectors are promising for applications in the mid-infrared requiring sub-nanosecond timing, ultra-high gain stability, low dark counts, and high efficiency, such as chemical sensing, LIDAR, dark matter searches, and exoplanet spectroscopy.

利用硅化钨超导纳米线探测器在10 μm波长以内的中红外单光子探测。

我们开发了基于硅化钨的超导纳米线单光子探测器，该探测器在10 μm波长范围内具有饱和内部探测效率。这些探测器有望应用于需要亚纳秒定时、超高增益稳定性、低暗计数和高效率的中红外，如化学传感、激光雷达、暗物质搜索和系外行星光谱学。
