Soliton propagation near zero-dispersion wavelength in birefringence fiber

From coupled nonlinear Schrodinger equation which describes the birefringence near zero-dispersion wavelength, we derive the evolution feature of soliton parameters and get the differential equation describing the evolution of interval between solitons along with propagation distance. At the same time, rye have made detailed numerical research on the propagation in dissipation system of standard fundamental soliton. The result shows that for attractive potential, the distance of oscillation increases along with the loss increases. For repulsive potential, the distance of oscillation diverges faster along with the loss increases. If selecting the proper optical fiber of high-order dispersion, the interaction between solitons in birefringence fiber can be eliminated.
