Abstract :
We demonstrate a multiwavelength pulse source which utilizes the super-continuum generated in a normal group-velocity dispersion fiber and an arrayed-waveguide grating filter. Over 20-channels of pulse train with a repetition rate of 10 GHz are realized, and each channel has almost the same pulsewidth. This uniformity originates from the fact that the super-continuum pulse generated in a normal-dispersion fiber has a rectangular waveform and a linear chirp.
