Pedestal suppression of high-order compressed solitons by using the bistability of the nonlinear Fabry-Perot cavity

It is well known that the compressed pulse by the high-order soliton effect in dispersion-shifted fiber (DSF) accompanies by undesired pedestals. In this paper, a novel method by combining a nonlinear Fabry-Perot cavity (NLFPC) and EDFA is proposed for pedestal suppression, which is based on the optical bistability effect of the NLFPC. The numerical simulations demonstrate that obvious pedestal suppression can be realized by selecting reasonably the facet reflectivity of the NLFPC, and the detuning between the central frequency of the input pulse and the resonant frequency of the NLFPC.
