Optimization of the carrier pulse shape in dispersion managed transmission systems

It has been shown that in dispersion-managed systems, performance can be improved through optimization of the carrier pulse shape. For quasi-linear systems, where intra-channel four wave mixing (ICFWM) is the main limitation, super Gaussian shaped pulses reduced the nonlinear-phase shift that consequently diminishes ICFWM. In the case of soliton-like propagation, interactions between neighboring pulses can be reduced by using parabolic shaped pulses, which have shorter pulse tails.
