  • All silicon broadband ultra-violet metasurfaces
    Patent number: 11402543
    Abstract: A device has a substrate transparent to ultraviolet (UV) light, and at least one metalens formed of a material having large permittivity of UV light on the substrate. A device has a UV reflector, a UV transparent film on the reflector, and at least one metalens formed of a material having large permittivity of UV light on the film.
    Type: Grant

  • MEMS optical switch with dual cantilever couplers
    Patent number: 11307483
    Abstract: An optical switch includes a bus waveguide and an optical antenna supported by a substrate, a first and second coupling waveguide, a first and second actuation electrode, and a first and second reaction electrode. The first coupling waveguide is disposed parallel with the substrate and aligned with the bus waveguide. The first reaction electrode is coupled with, and adjacent to, the first coupling waveguide. The second coupling waveguide is optically connected with the first coupling waveguide and suspended over and configured to optically couple with the optical antenna. The second reaction electrode is coupled with, and adjacent to, the second coupling waveguide. The first and second actuation electrodes are supported by the substrate and configured to control the position of the first and second coupling waveguide, respectively, relative to the bus waveguide and optical antenna, via the first and second reaction electrodes.
