PT Unknown AU Goltsman, G TI Superconducting thin film as infrared heterodyne and direct detectors SE 16th ISEC PY 2017 BP 1 EP 3 DI 10.1109/ISEC.2017.8314188 DE optical waveguide SSPD; SNSPD AB We present our recent achievements in the development of superconducting nanowire single-photon detectors (SNSPDs) integrated with optical waveguides on a chip. We demonstrate both single-photon counting with up to 90% on-chip-quantum-efficiency (OCDE), and the heterodyne mixing with a close to the quantum limit sensitivity at the telecommunication wavelength using single device.
