Title: Superconducting single-photon ultrathin NbN film detector

Abstract

Superconducting single-photon ultrathin NbN film detectors are studied. The development of manufacturing technology of detectors and the reduction of their operating temperature down to 2 K resulted in a considerable increase in their quantum efficiency, which reached in the visible region (at 0.56 {mu}m) 30%-40%, i.e., achieved the limit determined by the absorption coefficient of the film. The quantum efficiency exponentially decreases with increasing wavelength, being equal to {approx}20% at 1.55 {mu}m and {approx}0.02% at 5 {mu}m. For the dark count rate of {approx}10{sup -4}s{sup -1}, the experimental equivalent noise power was 1.5x10{sup -20} W Hz{sup -1/2}; it can be decreased in the future down to the record low value of 5x10{sup -21} W Hz{sup -1/2}. The time resolution of the detector is 30 ps. (fourth seminar to the memory of d.n. klyshko)
