  • Fast calibration and programming optical components
    Patent number: 9543737
    Abstract: A method and apparatus for calibrating and controlling tunable lasers are disclosed. Multiple methodologies disclosed herein may be used, alone or in combination, which significantly speed up a calibration time and thus provide a significant advantage over existing technology in calibrating the tunable lasers. Certain methodologies benefit from a unique design of the tunable lasers that couple two or more optical facets to an output. The tunable lasers may be equipped with two or more sampled grating distributed Bragg reflector (SGDBR) mirrors and may include Semiconductor Optical Amplifiers (SOAs) after the SGDBR mirrors.
    Type: Grant

    Date of Patent: January 10, 2017
    Assignee: OE SOLUTIONS AMERICA, INC.
    Inventors: Daniel Blumenthal, Holger Klein, Chad Althouse, Todd Chicci, Patrick Bybee, Henrik Poulsen, Sarat Chandra Gundavarapu
