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: 10459138Abstract: 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).Type: GrantFiled: January 24, 2019Date of Patent: October 29, 2019Assignee: Moxtek, Inc.Inventors: Ted Wangensteen, Bin Wang, Matt George, Paul Steven Mills, Arash Farhang
