The facet dimensions can be greater than half the wavelength of incident light (27) such that the facets substantially diffract light (29). A polarizing wire-grid layer (25, 92) comprised of an array of elongated parallel conductive wires (12) 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 (29) having an s- polarization orientation and substantially transmitting a portion of light (28) having a p- polarization orientation.
