Patent 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.
