  • Materials for metalenses, through-waveguide reflective metasurface couplers, and other metasurfaces
    Patent number: 11933940
    Abstract: Systems and methods are described herein for manufacturing high-index, low-absorption materials for use in visible light optical metasurfaces. Methods of manufacturing or forming hydrogenated amorphous silicon (a-Si:H), silicon-rich nitride (SRN), and hydrogenated silicon-rich nitride (SRN:H) are described herein that exhibit high indices of refraction and low extinction coefficients for visible wavelengths of optical radiation. Optical metasurfaces, including optical metalenses and waveguide couplers, are described herein that utilize the a-Si:H, SRN, and/or SRN:H materials.
    Type: Grant
    Filed: September 14, 2023
    Date of Patent: March 19, 2024
    Assignee: Imagia, Inc.
    Inventors: Gregory Kress, Heydar Honarvar Nazari, Arindom Datta, Erik Shipton, Abdoulaye Ndao
