Abstract
The wire grid polarizer (WGP) comprises an array of parallel, elongated nanostructures located over a surface of a transparent substrate and a plurality of spaces, including a space between adjacent nanostructures. Each of the nanostructures can include (1) a plurality of parallel, elongated wires located on the substrate, including an inner-pair located between an outer-pair; (2) lateral-gaps between each wire of the outer-pair and an adjacent wire of the inner-pair; (3) and a center-gap between the two wires of the inner-pair.
