Soliton is a nonlinear wave which has the properties of propagating without change of its properties (shape, velocity etc) and stable against mutual collisions and retains their identities. Nowadays solitons are becoming a more and more important development in the optical communications field. In this final year project, solitons in dispersion-managed fiber lasers with different net cavity dispersion were investigated numerically by examining the formation of the soliton in different group velocity dispersion regime, aiming at a better understanding of the soliton operation within a dispersion-managed system and the mixed effects of nonlinearity, dispersion, gain and loss. Based on our simulation and numerical analysis, we show that solitons could be formed in passively mode-locked fiber lasers with normal dispersion regime, as well as with anomalous dispersion area, and they exhibit distinguished properties and characteristics.
