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.
