Gustav Mueller 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).

  • Controllable integrated optical Mach-Zehnder interferometer
    Patent number: 5151959
    Abstract: An integrated-optical interferometer is formed of two strip waveguides integrated on a substrate. A strip waveguide section of the interferometer is designed as a controllable strip waveguide, and the strip waveguides are passive strip waveguides outside of the section. In order to guarantee a largely polarization-dependent function of this interferometer and of an optical switch realized therewith, the passive waveguides comprise a defined, different strip waveguide structure than the controllable strip waveguide.
    Type: Grant

    Inventors: Gustav Mueller, Lothar Stoll
  • Integrated optical arrangement having at least one optical waveguide integrated on a substrate of a semiconductor material and the method of manufacture
    Patent number: 5125065
    Abstract: An integrated optical arrangement having at least one optical waveguide integrated a substrate of semiconductor material, characterized by the waveguide being a rib waveguide comprising the p-doped material disposed on a substrate which contains a waveguiding layer which is either an n-doped or an undoped material, said arrangement having either a pn or a pin junction between the p-doped material of the rib and the n-doped or undoped material of the waveguiding layer. In addition, a method for forming the various layer is disclosed.

  • Laser diode
    Patent number: 4792959
    Abstract: A laser diode is provided having a strip-shaped web based on the principle of a metal clad ridge waveguide laser diode with a strip-shaped web width of less than 10 .mu.m. At least one lateral web extends laterally of the strip-shaped web and serves as a carrier for an electrical connection between the metal cladding of the strip-shaped web and a contacting surface for an electrical lead.
