Simple rules and chart to design an all-optical SPM-based regenerator

The all-optical regenerator based on self-phase modulation (SPM) and off-centered filtering has attracted much interest thank to its simplicity and efficiency. The regenerator includes a nonlinear fibre and an off- centered filter placed at the output of the fibre. Designing the regenerator consists to find the appropriate set of parameters for the nonlinear fibre and the filter to have an S-shape transmission function as represented. Provost et al. have proposed original scaling rules to achieve this purpose.
