Fast and high efficiency superconducting nanowire single-photon detector at 630 nm wavelength
Abstract:
Fast and high efficiency single-photon detectors have important applications in the fields of life science and quantum information. We report, herein, a serially connected two superconducting nanowire avalanche photon detector (SC2-SNAP) fabricated on a dielectric mirror aiming to 630 nm wavelength. This detector shows system detection efficiency (SDE) of 84.8% at a dark count rate of 10 Hz and offers fast detection speed while maintaining a high SDE, where the counting rate reaches 53.9 MHz at an SDE of 60%. This fast and high efficiency single-photon detector may find applications in fluorescence correlation spectroscopy and quantum key distribution.
