摘要：
A selectively absorptive, mulitlayer wire-grid polarizer (10a-e) for polarizing incident light (12) includes a stack of thin film layers (18) disposed over a substrate (14), including a wire-grid array of elongated metal elements (26) having 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 (30a-c) can include a dielectric array of non-metal elements. One of the layers (34a-b) includes a material that is optically absorptive to the incident light.
