Abstract

The propagation and the stability of sequences of dissipative solitons in fibers with gain, saturable absorption, and spectral band limitation of radiation has been analysed. The spectrum dependence for a gain is approximated by a squared frequency dispersion. The spectrum-dependent loss related with the additional spectral limitatiaon is modeled by a fourth order frequency one. It is found that the combined action of the nonlinear refractive index inducing a frequency soliton chirp and of the indicated spectral limitation causes the negative feedback. By the action of this negative feedback and the positive feedback due to saturable absorption on propagating pulses, the dissipative soliton sequences is stabilized: the weak noise pulses are suppressed, the powerful signal solitons with different amplitudes are equalized. The found stabilization can present interest for a management of sequences of dissipative solitons in fiber lines.
