Thomas P. Schrans 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).

  • Semiconductor laser device and circuit for and method of driving same
    Patent number: 8913638
    Abstract: A directly driven laser includes multiple contacts, with at least one of the contacts for injecting current into the laser such that the laser reaches at least a lasing threshold and at least one of the contacts for providing a data signal to the laser. In some embodiments a differential data signal is effectively provided to a front and a rear section of the laser, while lasing threshold current is provided to a central portion of the laser.
    Type: Grant
    Filed: August 23, 2012
    Date of Patent: December 16, 2014
    Assignee: Kaiam Corp.
    Inventors: Gideon Yoffe, Bardia Pezeshki, Thomas P. Schrans
