In fiber with randomly varying birefringence, the interactions between solitons in the same polarization channel and in two orthogonal polarization channels are investigated by the use of numerical simulations. The results obtained show that the interaction between solitons in the same polarization channel is weaker than that of solitons in two orthogonal polarization channels. The strong interaction leads to soliton splitting and soliton propagation instability, and the randomly varying birefringence enhances the interaction. A nonlinear gain combined with the filter can be used to effectively suppress the interactions and stabilize the soliton propagation. © 2001 John Wiley & Sons, Inc.
