Effect of Guiding Filters on the Behavior of Dispersion-Managed Solitons

We show that guiding filters fundamentally alter the behavior of dispersion-managed solitons by making the pulse energy nearly independent of path-average dispersion (D bar) in the neighborhood of (D bar) = 0. This fact enables the design of maps permitting adequate pulse energy with narrow-bandwidth, temporally-broad pulses, for the attainment of high spectral efficiency and reduced nonlinear penalties in wavelength division multiplexing.
