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.

Wire grid polarizer heat sink having specified reflective layer, absorptive layer, and heat-dissipation layer

A wire grid polarizer and method of making a wire grid polarizer can protect delicate wires of the wire grid polarizer from damage. The wire grid polarizer can include a protective-layer located on an array of wires. The array of wires can further be protected by a chemical coating on an inside surface of the air-filled channels, closed ends of the air-filled channels, damaged wires of the array of wires in a line parallel to an edge of the wire grid polarizer, or combinations thereof. The method can include (i) providing the wire grid polarizer, (ii) applying the protective-layer, by physical vapor deposition or chemical vapor deposition but excluding atomic layer deposition, onto the array of wires, (iii) cutting the wire grid polarizer wafer into multiple wire grid polarizer parts, then (iv) protecting the array of wires.

Wire grid polarizer with protected wires

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.
