Patent number: 11929446Abstract: Provided is a preparation method of a detector material. The present disclosure epitaxially grows a buffer layer on a surface of a gallium arsenide substrate, deposits a silicon dioxide layer on the buffer layer, and etches the silicon dioxide layer on the buffer layer according to a strip pattern by photolithography and etching to form strip growth regions with continuous changes in width.

Because of the same mobility of atoms arriving at the surface of the substrate, numbers of atoms migrating to the strip growth regions are different due to different widths of the strip growth regions, such that compositions of the material change with the widths of the strip growth regions or a layer thickness changes with the widths of the strip growth regions.Type: GrantFiled: November 8, 2022Date of Patent: March 12, 2024Assignee: CHANGCHUN UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Qun Hao, Zhipeng Wei, Jilong Tang, Huimin Jia, Lei Liao, Kexue Li, Fengyuan Lin, Rui Chen, Shichen Su, Shuangpeng Wang

Publication number: 20240076231Abstract: A proposed fabrication technique for a polarization-absorbing wire grid polarizer avoids the need to etch through the multilayer stack of materials to form the grid structure. Initial reflective metal and dielectric buffer layers are patterned and etched in a conventional manner to create the desired grid topology. A small-angle coating process is then used to complete the fabrication process by first coating the top surface of the patterned dielectric with a polarization-absorbing metal. A second coating process is used to cover the created metal coating with a dielectric cladding material. Maintaining a small angle of incidence between the coating source and the wire grid structure ensures that top portions of the grid are suitably covered to create the desired multilayer wire configuration.Type: ApplicationFiled: August 23, 2023Publication date: March 7, 2024Applicant: II-VI Delaware, Inc.Inventors: Junjie Yao, Jianying Zhang, Xiaolian Zhou, Xu Jia, Lei Lin, Guanglong Yu
