Abstract
A diffusive device has an array of discrete facets which may be of a size and pattern similar to a fractal. The facet dimensions can be greater than half the wavelength of incident light such that the facets substantially diffract light. A polarizing wire-grid layer comprised of an array of elongated parallel conductive wires with a period less than half the wavelength of incident light may be disposed between, beneath, or above the facets. The wire-grid polarizes the light by substantially reflecting light having an s-polarization orientation and substantially transmitting a portion of light having a p-polarization orientation.
