Abstract :
The performance of self-phase modulation (SPM)-impaired systems can be improved significantly by adjusting the net residual dispersion (NRD) of the systems. In this paper, we propose a novel approach to optimize the NRD for SPM-impaired systems. We find that in SPM-impaired system, the optimal NRD can be obtained by minimizing the output distortion of a single pulse. Using a perturbation theory, a semianalytical expression is derived to calculate the output distortion of a single pulse. With the obtained expression, the NRD of SPM-impaired dispersion-managed systems can be optimized conveniently. Compared to previous methods, the present method is simple and fast. The validity of this method is verified by numerical simulations for various SPM-impaired systems
