摘要: We consider optical pulse propagation in an Erbium doped inhomogeneous lossy fiber with time dependent phase modulation, which is governed by a system of Generalized Inhomogeneous Nonlinear Schrodinger Maxwell–Bloch (GINLS–MB) equation. Multi-soliton studied analytically means deriving associated Lax pair and the soliton solutions are obtained using Darboux transformation. By suitably adjusting group velocity dispersion nonlinearity parameter, we discuss various dynamics such as periodic distributed amplification, compression etc. In each case, demonstrate influence parameter. Finally investigate through nonlinear tunneling.
