摘要：

We consider the coupled higher order nonlinear Schrodinger (CHNLS) equations which govern the propagation of the fields in a birefringent fiber with all higher order effects like the third order dispersion, Kerr dispersion, and stimulated Raman scattering. We generalize the 2 x 2 Ablowitz-Kaup-Newell-Segur method to the 5 X 5 eigenvalue problem and construct the Lax pair. The exact soliton solutions are explicitly obtained using the Darboux-Backlund transformation. A similar case of study is extended to three coupled HNLS equations and hence generalized to N-coupled equations.
