Nina Owschimikow 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).

  • Nonlinear semiconductor light sources
    Patent number: 6816530
    Abstract: A monolithic apparatus has a laser optical cavity. The laser optical cavity has a multi-layer structure that includes a first active semiconductor multi-layer and a second semiconductor multi-layer. The second semiconductor multi-layer is located laterally adjacent to the first active semiconductor multi-layer. The first active semiconductor multi-layer includes a sequence of quantum well structures that produce light of a lasing frequency in response to being electrically pumped. The second semiconductor multi-layer includes a sequence of quantum well structures and is configured to both absorb light of the lasing frequency and produce one of parametric light and harmonic light in response to absorbing light of the lasing frequency.
    Type: Grant
    Filed: September 30, 2002
    Date of Patent: November 9, 2004
    Assignee: Lucent Technologies Inc.
    Inventors: Federico Capasso, Alfred Yi Cho, Raffaele Colombelli, Claire F Gmachl, Nina Owschimikow, Deborah Lee Sivco
