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: The wire grid polarizer (WGP) comprises an array of parallel, elongated nanostructures located over a surface of a transparent substrate and a plurality of spaces, including a space between adjacent nanostructures. Each of the nanostructures can include (1) a plurality of parallel, elongated wires located on the substrate, including an inner-pair located between an outer-pair; (2) lateral-gaps between each wire of the outer-pair and an adjacent wire of the inner-pair; (3) and a center-gap between the two wires of the inner-pair.

Abstract: A cube polarizing beam splitter (PBS) can have one or more of the following characteristics: high contrast (Tp/Ts), acceptance of a large range of incident angles, broadband, and symmetry. The cube PBS can include a pair of wire-grid polarizers sandwiched between a first prism and a second prism. There can be a boundary layer between the wire-grid polarizers. An optical path length of a transmitted beam can be equal or very close to an optical path length of a reflected beam.

Abstract: A wire grid polarizer (WGP) 10 can include a reflective layer 15 sandwiched on each side by a pair of transparent layers (11-12 and 13-14). An index of refraction of each outer transparent layer 11 or 14 can be greater than an index of refraction of the adjacent inner transparent layer 12 or 13, respectively. Material composition of the outer transparent layers 11 and 14 can be the same, 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.

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: Cube polarizers can be designed for substantially equal optical path lengths of a reflected beam and a transmitted beam. For example, d11 of FIG. 1 can define a distance between a plane (face plane2) of the outer face (outer face2) of a second prism 16 and the first edge (first edge1) of the first prism, and d11 can be less than 400 micrometers. As another example, an optical path length differential between a transmitted beam and a reflected beam (|OPLT−OPLR|) can be
