Patents by Inventor Tobias J. Kippenberg

Tobias J. Kippenberg 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: 7545843
    Abstract: A micro-cavity resonator including a micro-cavity capable of high and ultra-high Q values and a silicon substrate. Portions of the silicon substrate located below a periphery of the micro-cavity are removed to form a pillar, which supports the micro-cavity. Optical energy travels along an inner surface of the micro-cavity.
    Type: Grant

  • Patent number: 7003002
    Abstract: The present invention is a Raman laser and methods related thereto. In the preferred embodiments, the Raman laser comprises a laser pump signal in a fiber waveguide which is optically coupled to a micro-resonator through a fiber taper. The micro-resonator is constructed from a material that has a high Q when it is formed into a micro-resonator and is phase matched to the waveguide. The lasing frequency can be determined based upon the pump input or the micro-resonator material. In the preferred embodiments, the micro-resonator is constructed from a fused silica material. The present invention provides a compact laser with improved emissions and coupling efficiencies and the ability to use stimulated Raman scattering effects to create lasers having frequencies that are otherwise difficult to obtain. Alternative configurations include multiple micro-resonators on a single fiber waveguide and/or utilizing multiple waveguides attached to one or more micro-resonators.
