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

The TE polarized light is divided into two beams of TE polarized branch light. The TM polarized light is divided into two beams of TM polarized branch light. One of the two beams of TM polarized branch light is divided into two beams of first TM polarized sub-branch light. Another of the two beams of TM polarized branch light is divided into two beams of second TM polarized sub-branch light.Type: GrantFiled: April 22, 2020Date of Patent: March 21, 2023Assignee: ZHEJIANG UNIVERSITYInventors: Xuan She, Junjie Yao, Kan Chen, Tengchao Huang, Xiaowu Shu

Publication number: 20220175253Abstract: Reversibly switchable photoacoustic tomography (RS-PAT), a photoacoustic technique with enhanced sensitivity and resolution, is disclosed. RS-PAT utilizes a subtractive process for the formation of a photoacoustic image of a region containing a plurality of switchable photoacoustic probes. In various aspects, the photoacoustic detection in RS-PAT imaging occurs minimally twice: a first image obtained when the photoacoustic probe is in active (absorbing or ON) state and a second image obtained when the photoacoustic probe is in an inactive (less-absorbing or OFF) state. Subtraction of the second image from the first image is used to obtain the RS-PAT image.Type: ApplicationFiled: November 10, 2021Publication date: June 9, 2022Inventors: Vladislav V.

One example method for refining homonyms and synonyms in a plurality of tags may include receiving, by a tag refinement system, a plurality of tagging actions each of which associates one or more of the plurality of tags with a digital object. The method may further include extracting, by the tag refinement system, a first subset of tags from the plurality of tags, wherein the first subset of tags have a higher collective relativity-similarity score comparing to a second subset of tags selected from the plurality of tags, and the first subset of tags, different from the second subset of tags, have a same predetermined tag count as the second subset of tags.Type: ApplicationFiled: June 29, 2016Publication date: October 20, 2016Applicant: Peking UniversityInventors: Bin CUI, Junjie YAO
