Publication number: 20250053082Abstract: The present disclosure generally relates to methods of forming optical devices comprising nanostructures disposed on transparent substrates. A first process of forming the nanostructures comprises depositing a first layer of a first material on a glass substrate, forming one or more trenches in the first layer, and depositing a second layer of a second material in the one or more holes to trenches a first alternating layer of alternating first portions of the first material and second portions of the second material. The first process is repeated one or more times to form additional alternating layers over the first alternating layer. Each first portion of each alternating layer is disposed in contact with and offset a distance from an adjacent first portion in adjacent alternating layers. A second process comprises removing either the first or the second portions from each alternating layer to form the plurality of nanostructures.Type: ApplicationFiled: October 31, 2024Publication date: February 13, 2025Inventors: Yongan XU, Jinxin FU, Jhenghan YANG, Ludovic GODET

Patent number: 11714244Abstract: Disclosed are an optical assembly and a manufacturing method therefor. The optical assembly comprises a laser component (2) and a crystal (1). The crystal (1) is disposed on the laser component (2). The laser component (2) is used to produce a laser beam. The crystal (1) is used to split the laser beam incident onto the crystal (1) so as to generate a first beam (15) and a second beam (16). The first beam (15) is used for front light emission and the second beam (16) is used for backlight monitoring. The optical assembly can split a laser beam to achieve the backlight monitoring function without adding a splitter film. It has good stability in light splitting and reduces the risk of failure in an optical device.Type: GrantFiled: December 25, 2018Date of Patent: August 1, 2023Inventors: Fen Xiong, Tingyu Li, Rikai Zhou, Yongan Fu, Liping Sun

Patent number: 11675148Abstract: An optical-path-displacement-compensation-based emission optical power stabilization assembly, comprising: a laser, a lens, and an optical fiber coupling port disposed on a first substrate and a second substrate according to a preset arrangement scheme, wherein an expansion coefficient of the second substrate is larger than that of the first substrate, and the preset arrangement scheme enables initial distances between the laser and the lens, between the lens and the optical fiber coupling port, and/or between the laser and the optical fiber coupling port to differ from respective optical coupling distances from an optical coupling point by a preset value, thereby ensuring that a coupling loss on an optical path changes along with the temperature, forming a complementary effect with respect to an optical power-temperature curve of the laser, which reduces a temperature-caused fluctuation of the emission optical power of an optical assembly.Type: GrantFiled: December 13, 2019Date of Patent: June 13, 2023Inventors: Hu Zhu, Shujian Du, Yanling Guo, Hongyang Liu, Rikai Zhou, Yongan Fu, Liping Sun
