Patent number: 10268046Abstract: 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 < 0.5 * t * n p 2 ; where t is a thickness of the substrate between the first surface and the second surface of the substrate and np is an index of refraction of the first prism.Type: GrantFiled: November 21, 2016Date of Patent: April 23, 2019Assignee: Moxtek, Inc.Inventors: Austin Huang, Dean Probst, Bin Wang, Hua Li

Patent number: 9354374Abstract: 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.Type: GrantFiled: August 27, 2014Date of Patent: May 31, 2016Assignee: Moxtek, Inc.Inventors: Bin Wang, Ted Wangensteen, Rumyana Petrova, Mike Black, Steven Marks, Dean Probst, Mark Alan Davis

Patent number: 9348076Abstract: 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.Type: GrantFiled: August 27, 2014Date of Patent: May 24, 2016Assignee: Moxtek, Inc.Inventors: Bin Wang, Ted Wangensteen, Rumyana Petrova, Mike Black, Steven Marks, Dean Probst

Publication number: 20120156845Abstract: A method for forming a field effect transistor and Schottky diode includes forming a well region in a first portion of a silicon region where the field effect transistor is to be formed but not in a second portion of the silicon region where the Schottky diode is to be formed. Gate trenches are formed extending into the silicon region. A recessed gate is formed in each gate trench. A dielectric cap is formed over each recessed gate. Exposed surfaces of the well region are recessed to form a recess between every two adjacent trenches.
