Makoto Oomori 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).

  • Method for producing optical waveguides, optical waveguides and frequency converting devices
    Patent number: 6836354
    Abstract: A method for producing an optical waveguide by irradiating a laser beam onto an oxide single crystal material includes a means by which the scattering of light from the surface of the waveguide may be prevented when light is transmitted through the waveguide. A laser beam is irradiated onto an oxide single crystal to from an optical waveguide portion defined by laser working faces, which are then subjected to a wet etching process using, for example, a strong alkaline solution.
    Type: Grant

    Abstract: The object of the invention is to provide a method for producing an optical waveguide by irradiating laser beam onto an oxide single crystal material so that the scattering of light from the surface of the waveguide may be prevented when light is transmitted through the waveguide. Laser beam is irradiated onto an oxide single crystal to from an optical waveguide portion 9A defined by laser working faces 9a and 9b, which are then subjected to a wet etching process using, for example, a strong alkaline solution.
