Abstract
A superconducting nanowire single photon detector (SNSPD) device includes a substrate, a distributed Bragg reflector on the substrate, a seed layer of a metal nitride on the distributed Bragg reflector, and a superconductive wire on the seed layer. The distributed Bragg reflector includes a plurality of bi-layers, each bi-layer including lower layer of a first material and an upper layer of a second material having a higher index of refraction than the first material. The wire is a metal nitride different from the metal nitride of the seed material.
