POLARIZER WITH WIRE PAIR OVER RIB

摘要

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.

1. A wire grid polarizer comprising:
a. an array of parallel, elongated nano-structures disposed over a surface of a substrate, each of the nano-structures including:
i. a first rib disposed over the surface of the substrate;ii. a pair of parallel, elongated wires, each laterally oriented with respect to one another, and disposed over the first rib;iii. a first gap between the pair of wires; andiv. each wire of the pair of wires has two opposite sides substantially orthogonal to the surface of the substrate; b. a plurality of second gaps including a second gap disposed between adjacent first ribs; and c. the substrate being transmissive.
