Modulation instability effects on three-channel optically multiplexed communication systems

Four-wave mixing dynamics an analyzed on a three-channel optically multiple xed communication system. In the anomalous propagation regime, where modula tion instability effects are much stronger, energy interchange among signal channels tends to favor the central channel as opposed to the normal propa gation regime where the central channel is depleted. These results are expl ained both in terms of the phase-matched growth of generated spectral sideb ands and the three-channel modulation instability gain spectrum.
