An embedded, inverse wire-grid polarizer (WGP) includes ribs (13) located over a surface of a transparent substrate (11), gaps (16) between the ribs, and a fill-layer (15) substantially 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, E11 transmission can be greater than El. transmission. E11 is a polarization of light with an electric field oscillation parallel to a length L of the ribs, and El. is 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 (El. transmission > E11 transmission). |
