Abstract
A cube wire grid polarizer or an embedded wire grid polarizer can include an adhesive-free, direct bond between the wire grid polarizer and piece(s) of glass. Consequently, index of refraction mismatch can be avoided and the polarizer can have improved high temperature tolerance. The polarizer can include multiple layers over the wire grid polarizer, with the top of these layers polished, then directly bonded to the piece of glass. Material of the top layer can be selected such that thickness of this layer is not critical, thus allowing polishing.
