  • Fabrication and replication of polymer optical waveguides
    Patent number: 9981408
    Abstract: Polymer optical waveguides can be produced by separating the processes into a distinct embossing process and a distinct UV exposure process. Separating the processes can create a more refined product and a more efficient process, thus eliminating the need for special polymer optical waveguide fabrication machinery.
    Type: Grant
    Filed: March 24, 2014
    Date of Patent: May 29, 2018
    Assignee: City University of Hong Kong
    Inventors: Wei Jin, Kin Seng Chiang, Hau Ping Andy Chan
