Optical Soliton Inelastic Interacitons in Nonlinear Schrödinger Equation with Variable Coefficients Model

Authors: Plastun A. S., Konyukhov A. I., Melnikov L. A., Zar’kov S. A.

It is shown that in systems described by nonlinear Schrödinger equation with variable coefficients, interaction of two solitons can carry an inelastic character. Inelastic collision solitons can lead to changes in their group velocities, amplitudes and durations. We consider some particular cases related to the separation of the soliton pair and formation of a bound state of two solitons. In the applied aspect these phenomena can be used to control the soliton interaction in optical fiber communications.

Authors: Dorokhova M. A., Konyukhov A. I., Melnikov L. A., Plastun A. S.

In this article the results of numerical modeling of soliton’s collision in dispersion oscillating fiber are presented. Nonlinear Schroedinger equation for modelling was used. Different propagation regimes of the couple of solitons are considered. One of these results is merging of two solitons into high-intensity pulse.
