Abstract
A superconducting nanowire single photon detector (SNSPD) device includes a substrate having a top surface, an optical waveguide on the top surface of the substrate to receive light propagating substantially parallel to the top surface of the substrate, a seed layer of metal nitride on the optical waveguide, and a superconductive wire on the seed layer. The superconductive wire is a metal nitride different from the metal nitride of the seed layer and is optically coupled to the optical waveguide.
