Modulation Instability in a dispersion oscillating fiber pumped by a broad band pulse
Résumé
We numerically investigate the modulation instability generated in a dispersion oscillating fiber pumped by a chirped pulse with a broad bandwidth. We highlight that the side bands are wide, not symmetric in frequency about the pump and several instantaneous side bands can spectrally overlap with each other in one side while they are well located in the other side. We also show that the spectral distribution can be intuitively explained with an analogy in which the fiber is pumped by a tuneable continuous wave.
