Abstract

The soliton propagation and interaction characteristics in the presence of spectral filtering, linear and nonlinear gain are investigated. We show that, as the linear gain vanishes, the steady-state soliton amplitude and inverse duration diverge. The nonlinear gain is shown to have a significant impact on the soliton interaction when the adjacent solitons have different phases or amplitudes. In these cases, a (pi) phase difference between adjacent pulses is induced when the nonlinear gain only partially replaces the linear gain. As the linear gain vanishes, the phase difference varies continuously and the solitons oscillate only slightly around their initial time separation.
