Chester Murley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Reflective diffraction grating and fabrication method
    Patent number: 10768349
    Abstract: A reflective diffraction grating and a fabrication method are provided. The reflective diffraction grating includes a substrate, a UV-absorbing layer, a grating layer having a binary surface-relief pattern formed therein, and a conforming reflective layer. Advantageously, the UV-absorbing layer absorbs light at a UV recording wavelength to minimize reflection thereof by the substrate during holographic patterning at the UV recording wavelength.
    Type: Grant
    Filed: June 30, 2017
    Date of Patent: September 8, 2020
    Assignee: Lumentum Operations LLC
    Inventors: John Michael Miller, Hery Djie, Patrick Lu, Xiaowei Guo, Qinghong Du, Eddie Chiu, Chester Murley

  • Wavelength dispersive device with temperature compensation
    Patent number: 7630599
    Abstract: The invention relates to fiber-optic wavelength dispersive devices incorporating a wavelength dispersive reflector that provides auto-compensation of variations of output spectral characteristic with temperature and includes a transmissive dispersion that is followed by a beam-folding reflecting surface in a double-pass configuration grating and is coupled to a wedged shaped prism.
