Computer Simulation of the Propagation and Interaction of Soliton Sequences in Nonlinear Optical Fibers

The results of the simulation of optical soliton propagation in nonlinear dispersive fiber with or without losses are presented. The propagation equation was modeled using the finite-difference-method. The propagation of fundamental soliton, higher order soliton and the sequence of up to five adjacent solitons was observed and analyzed for various initial conditions.
