Patents by Inventor Anatoliy A. SAVCHENKO

Anatoliy A. SAVCHENKO 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).

  • Patent number: 11152681
    Abstract: One feature pertains to an apparatus that includes apparatus that includes an evanescent field coupler having a first surface that evanescently couples light between the evanescent field coupler and an open dielectric resonator. The apparatus also includes a thin film coating covering at least a portion of the first surface of the evanescent field coupler. The thin film coating is specifically designed so that the thin film coating reflects light of a first wavelength.
    Type: Grant
    Filed: June 4, 2018
    Date of Patent: October 19, 2021

  • Publication number: 20190146091
    Abstract: The disclosure relates in some aspects to Light Detection and Ranging (LIDAR) for underwater applications. An exemplary LIDAR system described herein uses a green and/or blue semiconductor laser, which is self-injection locked using a high-quality factor micro-resonator, such as a whispering gallery mode (WGM) resonator. The self-injection locking results in a single mode operation of the laser and reduction of its linewidth. The self-injection allows transferring frequency modulation from the optical micro-resonator to the laser frequency without significant impact on the power of the laser. In some examples, the LIDAR operates in a continuous wave frequency modulated (CWFM) mode. The CWFM LIDAR may be used for ranging, velocity determination, etc., particularly for underwater applications and may be mounted to watercraft or to aircraft designed to fly over water to take underwater measurements.
