Abstract :
We investigate theoretically and experimentally the generation of dark soliton pulse trains at several gigahertz repetition rate by means of a fiber Bragg grating used as a passive filtering element at the output of a mode-locked laser. We show that a proper choice of the grating parameters allows for the transformation of bright pulse train into odd dark pulse trains with continuous-wave (CW) background.
