A wire grid polarizer (WGP) can be durable and have high performance. The WGP can comprise an array of wireson a substrate. An overcoat layercan be located at distal ends of the array of wiresand can span channelsbetween the wires. A conformal-coat layercan coat sidesand distal endsof the wiresbetween the wiresand the overcoat layer. The overcoat layer can comprise aluminum oxide. An antireflection layercan be located over the overcoat layer

A wire grid polarizer (WGP) can include a heat-dissipation layer. The heat-dissipation layer can enable the WGP to be able to endure high temperatures. The heat-dissipation layer can be located (a) over an array of wires and farther from a transparent substrate than the array of wires; or (b) between the array of wires and the transparent substrate. The heat-dissipation layer can be a continuous layer. The heat-dissipation layer can have a high electrical resistivity and a high coefficient of thermal conductivity.

An embedded wire-grid polarizer (WGP) can include ribslocated over a surface of a transparent substrate, gapsbetween the ribs, and a fill-layersubstantially filling the gaps. The fill-layer can have 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 &#x3e;Etransmission).

A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from oxidation and/or corrosion. The conformal-coating can include a barrier layer with at least one: of aluminum oxide, silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, hafnium oxide, and zirconium oxide. A method of making a WGP can include applying the barrier layer over ribs of a WGP by vapor deposition.

Oxidation and moisture barrier layers for wire grid polarizer

A wire grid polarizer (WGP) can have a phosphonate conformal-coating to protect the WGP from at least one of the following: corrosion, dust, and damage due to tensile forces in a liquid on the WGP. The conformal-coating can include a chemical: where Rcan include a hydrophobic group, Z can include a bond to the ribs, and Rcan be any suitable chemical element or group. A method of applying a phosphonate conformal-coating over a WGP can include exposing the WGP to (R)PO(R)(R), where: i is 1 or 2, j is 1 or 2, k is 0 or 1, and i+j+k=3; each Rcan independently include a hydrophobic group; Rcan include a phosphonate-reactive-group; each Rcan independently include an alkyl group, an aryl group, or combinations thereof; and each R, if any, can independently be any suitable chemical element or group.

Wire grid polarizers, and methods of making wire grid polarizers, including an array of parallel, elongated nano-structures disposed over a surface of a substrate. Each of the nano-structures can include a first rib disposed over a surface of a substrate and a pair of parallel, elongated wires, each laterally oriented with respect to one another, and disposed over the first rib. The wire grid polarizers can be durable with high transmission of one polarization of light, high contrast, and/or small pitch. The wire grid polarizers can also have high absorption or high reflection of an opposite polarization of light.

Polarizer with wire pair over rib

A wire grid polarizer comprising an array of parallel, elongated nano-structures disposed over a surface of a substrate. Each of the nano-structures can include a pair of parallel, elongated wires (or top ribs), each oriented laterally with respect to one another. There can be a first gap disposed between the pair of wires (or top ribs). Each of the nano-structures can be separated from an adjacent nano-structure by a second gap disposed between adjacent nanostructures, and thus between adjacent pairs of wires. A first gap width of the first gap can be different than a second gap width of the second gap. Also included are methods of making wire grid polarizers.
