Abstract: A wire grid polarizer (WGP) can have improved performance due to a high aspect ratio (e.g. >3, >5, >10, >15, >20, or >30), where aspect ratio equals T/W, T is a sum of a thickness of wires of the first array 11 plus a thickness of wires of the second array 12 (i.e. T=Th11+Th12), and W is a maximum width of wires of the first array 11 and/or of the second array 12. Such high aspect ratio can be achieved with two arrays of wires 11 and 12, each capped by a thin film 01 and 02.

Abstract: A wire grid polarizer (WGP) 10 can include wires 15 sandwiched between a first pair of thin-film layers 21 (with a first transparent layer 11 and a second transparent layer 12) and a second pair of thin-film layers 22 (with a third transparent layer 13 and a fourth transparent layer 14). An index of refraction of each outer transparent layer 11 and 14 can be greater than an index of refraction of the adjacent inner transparent layer 12 and 13, respectively. Material composition of the outer transparent layers 11 and 14 can be the same and material composition of the adjacent inner transparent layers 12 and 13 can be the same. There can be high reflection of one polarization (e.g. Rs1>93% and Rs2>93%) for light incident on either side of the WGP. The wires 15 can be embedded for protection.

Abstract: An embedded wire-grid polarizer (WGP) can include 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 can have 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: A wire grid polarizer comprising on array of parallel, elongated first rib groups disposed over a substrate. Each first rib group can comprise a central first transmissive rib and a pair of first wires including a first wire disposed along each side of the first transmisslve rib. A first dielectric material can substantially fill first gaps between each rib group and an adjacent rib group. An array of parallel, elongated second wires can be disposed over the rib groups and the first dielectric material. The first wires or the second wires can be absorptive and the other of the first wires or the second wires can be reflective.

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).
