  • Reflective wire grid polarizer with shaped ribs
    Patent number: 11988859
    Abstract: A reflective wire grid polarizer (WGP) can include an array of wires 12 on a face of a substrate 11, with channels 15 between adjacent wires 12. The wires 12 can have certain characteristics for WGP performance, such as index of refraction, alternating high/low index continuous thin films, thickness of layer(s), duty cycle, reflective rib shape, a curved side of transparent ribs 21 or 32, aspect ratio, or combinations thereof.
    Type: Grant
    Filed: October 26, 2022
    Date of Patent: May 21, 2024
    Assignee: Moxtek, Inc.
    Inventors: Daniel Bacon-Brown, Michael Black, R. Stewart Nielson, Bradley R. Williams, Benjamin Downard, Jeffrey H. Rice, Jim Pierce
