PT Unknown AU Zolotov, P Vakhtomin, Y Divochiy, A Seleznev, V Morozov, P Smirnov, K TI High-efficiency single-photon detectors based on NbN films PY 2013 DI 10.13140/RG.2.2.21142.96326 DE SSPD; SNSPD AB We present our resent results in development and testing of Superconducting Single-Photon Detectors (SSPD) with detection efficiencies greater than 85%. High values of obtained results are assigned to proposed design of the detector with integrated resonator structure, including two-layer optical cavity and anti-reflective coating (ARC). ER
