Soliton stability in optical transmission lines using semiconductor amplifiers and fast saturable absorbers

Abstract

Soliton stability has been examined in the cascaded transmission system based on the standard monomode fibers with in-line semiconductor optical amplifiers, sliding filters, and saturable absorbers (SAs). Stabilization of the pulse propagation in such a system can be achieved under a proper choice of the filter and SA parameters. Conditions of the stable propagation including a critical sliding rate are determined. Impact of the saturable absorber on the soliton stability has been investigated.
