Abstract :
We demonstrate supercontinuum generation in the telecom C-band in a photonic crystal fiber with all-normal group velocity dispersion. Pumping this fiber with picosecond pulses from a mode-locked semiconductor laser generates a 90 nm bandwidth continuum with typical self-phase-modulation characteristics. Over 1000 optical carriers with uniform precise channel spacing of 10 GHz are generated. In the experiment, the appearance of optical wave breaking is observed, and we provide an analysis of optical wave breaking of picosecond pulses in the photonic crystal fiber.
