FIELD: physics.
SUBSTANCE: ultrafast and ultrasensitive hybrid superconducting waveguide single-photon detector with a low dark count rate includes a sensitive nanowire from a superconducting NbN film located on a nanowave guide Si3N4, and a protective dielectric-metallic coating consisting of an SiO2 dielectric layer and a layer of Al metal deposited over the nanowire.
EFFECT: providing the possibility of reducing false triggering of a superconducting single-photon waveguide detector and increasing the sensitivity of the superconducting single-photon waveguide detector.
