Abstract
A reflection repressed wire-grid polarizer device for polarizing incident visible or infrared light and selectively repressing a reflected polarization includes at least three layers disposed on a substrate. A polarizing wire-grid layer has an array of parallel metal wires with a period less than half the wavelength of the incident light. A reflection-repressing layer or grid includes an inorganic and non-dielectric material which is optically absorptive of visible or infrared light. A dielectric layer or grid includes an inorganic and dielectric material.
