摘要：
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.
