  • Wire Grid Polarizer with High Reflectivity on Both Sides
    Publication number: 20190049645
    Abstract: A wire grid polarizer (WGP) 10 can include a reflective layer 15 sandwiched on each side by a pair of transparent layers (11-12 and 13-14). An index of refraction of each outer transparent layer 11 or 14 can be greater than an index of refraction of the adjacent inner transparent layer 12 or 13, respectively. Material composition of the outer transparent layers 11 and 14 can be the same, material composition of the adjacent inner transparent layers 12 and 13 can be the same. There can be high reflection of one polarization (e.g. Rs1>93% and Rs2>93%) for light incident on either side of the WGP.

  • Multiple-stack wire grid polarizer
    Patent number: 10139537
    Abstract: A wire grid polarizer (WGP) can have improved performance due to a high aspect ratio (e.g. >3, >5, >10, >15, >20, or >30), where aspect ratio equals T/W, T is a sum of a thickness of wires of the first array 11 plus a thickness of wires of the second array 12 (i.e. T=Th11+Th12), and W is a maximum width of wires of the first array 11 and/or of the second array 12. Such high aspect ratio can be achieved with two arrays of wires 11 and 12, each capped by a thin film 01 and 02.
