Soliton interaction and bound states in amplified-damped fiber systems.
It is shown that the soliton interaction can be signif icantly reduced in a system with ultimately stable soliton propagation. Moreover, under the action of strong filtering and nonlinear gain the soliton interaction can change sign from attraction to repulsion and vice versa. The formation of in-phase and out-of-phase bound states is also demonstrated.
