Patent number: 10690828Abstract: A cube wire grid polarizer or an embedded wire grid polarizer can include an adhesive-free, direct bond between the wire grid polarizer and piece(s) of glass. Consequently, index of refraction mismatch can be avoided and the polarizer can have improved high temperature tolerance. The polarizer can include multiple layers over the wire grid polarizer, with the top of these layers polished, then directly bonded to the piece of glass. Material of the top layer can be selected such that thickness of this layer is not critical, thus allowing polishing.Type: GrantFiled: July 6, 2018Date of Patent: June 23, 2020Assignee: Moxtek, Inc.Inventors: Shaun Ogden, Liang Gao, David Vern Nelson

Patent number: 10571614Abstract: 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.Type: GrantFiled: September 19, 2017Date of Patent: February 25, 2020Assignee: Moxek, Inc.Inventors: R.

Patent number: 10534120Abstract: 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.Type: GrantFiled: June 23, 2017Date of Patent: January 14, 2020Assignee: Moxtek, Inc.Inventors: R.

Publication number: 20190250421Abstract: 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.Type: ApplicationFiled: April 26, 2019Publication date: August 15, 2019Inventors: Shaun Ogden, Kerry Olivier, Hua Li, David S.

Patent number: 10310155Abstract: 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.Type: GrantFiled: October 17, 2018Date of Patent: June 4, 2019Assignee: Moxtek, Inc.Inventors: R.
