Bound States of dissipative solitons in optical fiber systems

摘要

In this paper we investigate the interaction between solitary-plain pulses (SP) of the quintic CGLE modified, which describes the soliton behaviour in the presence of spectral filtering, linear and nonlinear gains, and self-frequency shift (intrapulse Raman scattering). In particular, we look for a clear understanding of fundamental properties of the bound sates, especially as concerns their stability. We use the interaction plane (distance-phase difference) to analyze the dynamics of the two soliton system. We have found stable BS's of plain pulses when the phase difference between them is π / 2 + Δ, and Δ is a quantity that depends on a self-frequency shift coefficient.
