  • Polarizer with wire pair over rib
    Patent number: 9354374
    Abstract: Wire grid polarizers, and methods of making wire grid polarizers, including an array of parallel, elongated nano-structures disposed over a surface of a substrate. Each of the nano-structures can include a first rib disposed over a surface of a substrate and a pair of parallel, elongated wires, each laterally oriented with respect to one another, and disposed over the first rib. The wire grid polarizers can be durable with high transmission of one polarization of light, high contrast, and/or small pitch. The wire grid polarizers can also have high absorption or high reflection of an opposite polarization of light.
    Type: Grant

  • Polarizer with variable inter-wire distance
    Patent number: 9348076
    Abstract: A wire grid polarizer comprising an array of parallel, elongated nano-structures disposed over a surface of a substrate. Each of the nano-structures can include a pair of parallel, elongated wires (or top ribs), each oriented laterally with respect to one another. There can be a first gap disposed between the pair of wires (or top ribs). Each of the nano-structures can be separated from an adjacent nano-structure by a second gap disposed between adjacent nanostructures, and thus between adjacent pairs of wires. A first gap width of the first gap can be different than a second gap width of the second gap. Also included are methods of making wire grid polarizers.
