Df. Grosz et Hl. Fragnito, Spectral evolution of a two-channel WDM system in the presence of modulation in instability, MICROW OPT, 20(6), 1999, pp. 389-393
WDM optical communication systems operating in the anomalous dispersion reg
ion are shown to exhibit enhanced spectral broadening due to power phase-ma
tched pumping of generated four-wave mixing spectral sidebands. In this reg
ime, strong signal power modulation along the fiber takes place. We also sh
ow that nonzero dispersion-shifted fibers successfully overcome these probl
