Abstract
A nanowire photodetection system comprising an optical waveguide and superconducting nanowires. The optical waveguide is located on a substrate. The superconducting nanowires are electrically connected in parallel to connector wires located on both sides of the optical waveguide. A set of the superconducting nanowires cross a width of the optical waveguide and absorb a photon in the optical waveguide.
