  • Focused ion beam heater thermally tunable laser
    Patent number: 7224708
    Abstract: Platinum (Pt) thin film heaters are deposited by a focused ion beam for semiconductor manufacturing of thermally tunable distributed feedback lasers. An exemplar 1.3 ?m InGaAsP/InP laser is integrated with a tuning element having a wide wavelength tuning range of 4.9 nm, that is, 857 GHz, with a small heater current of 13.0 mA.
    Type: Grant
    Filed: August 30, 2004
    Date of Patent: May 29, 2007
    Assignee: The Aerospace Corporation
    Inventors: Yongkun Sin, Nathan Presser
