A wire-grid polarizer includes a wire-grid layer disposed over a substrate. A plurality of contiguous dielectric-grid layers are contiguous with one another and disposed directly on top of the wire-grid layer. The plurality of contiguous dielectric-grid layers includes different materials with different indices of refraction. The array of dielectric material elements and the array of metal elements are oriented substantially parallel with one another, and the arrays having substantially equal periods.

Multilayer wire-grid polarizer with off-set wire-grid and dielectric grid

A multilayer wire-grid polarizer for polarizing light includes a stack of thin film layers disposed over a substrate, including a wire-grid array of elongated metal elements having lengths longer than a wavelength of the light and a period less than half the wavelength of the light. One of the layers can include a thin film layer with a refractive index greater than a refractive index of the substrate. One of the thin film layers can include a dielectric array of non-metal elements.
