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

Abstract translation: 嵌入式反向线栅偏振器（WGP）包括位于透明基板11的表面上方的肋13，肋13之间的间隙16和基本上填充间隙16的填充层15.填充层具有相对的 高折射率，如大于1.4。 在入射到WGP的光的波长处，E∥传输可以大于E⊥传输。 E |是具有平行于肋的长度L的电场振荡的光的偏振，并且E⊥是具有垂直于肋的长度L的电场振荡的光的偏振。 这种嵌入的反向WGP对于具有高WGP性能的极化，对于难以用传统WGP（E⊥传输> E∥传输）极化的电磁光谱的小波长（高能量）区域（例如UV）是特别有用的。
