针对卫星激光测距（SLR）应用，设计并制作了波长为532 nm的超导纳米线单光子探测器（SNSPD）。NbN SNSPD制作在一维光子晶体上，灵敏区直径为42 μ m。该器件与多模光纤（φ = 50 μ m）耦合，在极低的暗计数率（1.5%）下，显示出75%的最大系统检测效率。
Superconducting nanowire single-photon detectors (SNSPDs) at a wavelength of 532 nm were designed and fabricated aiming to satellite laser ranging (SLR) applications. The NbN SNSPDs were fabricated on one-dimensional photonic crystals with a sensitive-area diameter of 42 mu m. The devices were coupled with multimode fiber (phi = 50 mu m) and exhibited a maximum system detection efficiency of 75% at an extremely low dark count rate of
