Zin Lin 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).

  • Topology optimized multi-layered meta-optics
    Patent number: 11835681
    Abstract: A multi-layered lens comprises a plurality of metasurface layers. At least some layers of the plurality of metasurface layers include features that exhibit angular phase controls. The angular phases of the at least some layers cause an angular aberration correction or an angle convergence that focuses light onto a focal point regardless of angles of incidence.
    Type: Grant
    Filed: June 19, 2018
    Date of Patent: December 5, 2023

  • Multi-mode cavities for high-efficiency nonlinear wavelength conversion formed with overlap optimization
    Patent number: 10353269
    Abstract: A fully confined dual frequency optical resonator configured for optical coupling to light having a first frequency ?1. The dual frequency optical resonator includes a plurality of alternating layer pairs configured in a grating configuration, each layer pair having a first layer formed of a first material and a second layer formed of a second material, the first material and second material being different materials. Each layer having a thickness different than a thickness of an adjacent layer to provide thereby aperiodic layer pairs, the thicknesses of adjacent layers being selected to create, via wave interference with each layer, optical resonances at the first frequency ?1 and a second frequency ?2 which is a harmonic of ?1, and to ensure a maximum spatial overlap between confined modes over the materials such that an overall quality factor Q of at least 1000 is achieved.

  • MULTI-MODE CAVITIES FOR HIGH-EFFICIENCY NONLINEAR WAVELENGTH CONVERSION FORMED WITH OVERLAP OPTIMIZATION
    Publication number: 20170248831
    Abstract: A dual frequency optical resonator configured for optical coupling to light having a first frequency ?1. The dual frequency optical resonator includes a plurality of alternating layer pairs stacked in a post configuration, each layer pair having a first layer formed of a first material and a second layer formed of a second material, the first material and second materials being different materials. The first layer has a first thickness and the second layer has a second thickness, the thicknesses of the first and second layer being selected to create optical resonances at the first frequency ?1 and a second frequency ?2 which is a harmonic of ?1 and the thicknesses of the first and second layer also being selected to enhance nonlinear coupling between the first frequency ?1 and a second frequency ?2.
