  • Multi-wavelength laser source
    Patent number: 7627006
    Abstract: A multi-wavelength laser source is provided including a pump laser unit, a gain section and an output. The pump laser unit generates an energy signal, which is applied to the gain section. The gain section includes a gain medium with having a superstructure grating forming a distributed Fabry-Perot-like structure. The superstructure grating causes a multi-wavelength laser signal to be generated when the energy signal is applied to the gain medium. The multi-wavelength laser signal is then released at the output.
    Type: Grant
    Filed: September 18, 2003
    Date of Patent: December 1, 2009
    Assignee: Universite Laval
