Intensity/Cross-Phase/intensity COnversion Filters in Dispersion Compensated Multiwavelenght transmission Systems.

摘要

In this paper we presetn an entirely linear model to accurately predict the phase and intensity distortion induced by the nonlinear effect of cross-phase modulation in dispresion compensated optical systems. Finally, we introduce a new model of the joint effect of cross-phase modulation and group-velocity dispersion in compensatedsystems, leading to a linear filter that, applied to the input intensities of the co-propagating channels, gives a very good approximation of the signal envelope at the end of the system.
