  • Light-emitting device having injection-lockable semiconductor ring laser monolithically integrated with master laser
    Patent number: 8009712
    Abstract: A semiconductor ring laser (SRL) section is monolithically integrated with a DFB or DBR master laser section on a semiconductor substrate of a light-emitting device to provide an injection locking mode of operation that can result in low-cost ultrafast (over 100 GHz) functional chip that will be easy to use in practice.
    Type: Grant
    Filed: July 24, 2009
    Date of Patent: August 30, 2011
    Assignee: STC.UNM
    Inventors: Marek A. Osinski, Omar K. Qassim, Nathan J. Withers, Gennady A. Smolyakov
