Abstract
An embedded, inverse wire-grid polarizer (WGP) includes ribslocated over a surface of a transparent substrate, gapsbetween the ribs, and a fill-layersubstantially filling the gaps. The fill-layer has a relatively high index of refraction, such as greater than 1.4. At a wavelength of light incident upon the WGP, Etransmission can be greater than Etransmission. Eis a polarization of light with an electric field oscillation parallel to a length L of the ribs, and Eis a polarization of light with an electric field oscillation perpendicular to a length L of the ribs. This embedded, inverse WGP is especially useful for polarizing, with high WGP performance, small wavelength (high-energy) regions of the electromagnetic spectrum (e.g. UV) which are difficult to polarize with conventional WGPs (Etransmission>Etransmission).
