  • SNSPD with integrated aluminum nitride seed or waveguide layer
    Patent number: 11788883
    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.
    Type: Grant
    Filed: January 29, 2021
    Date of Patent: October 17, 2023
    Assignee: Applied Materials, Inc.
    Inventors: Zihao Yang, Mingwei Zhu, Nag B. Patibandla, Nir Yahav, Robert Jan Visser, Adi de la Zerda
  • SNSPD WITH INTEGRATED ALUMINUM NITRIDE SEED OR WAVEGUIDE LAYER
    Publication number: 20230309420
    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.
