Dissipative optical solitons in passively mode-locked multilayer semiconductor laser waveguides

摘要

The results of studying the steady states for bright picosecond dissipative optical solitons, appearing in single-mode semiconductor laser waveguides structured in a direction of passing those pulses, is presented. This type of solitons occurs due to reshaping the incoming optical pulses via the passive mode-locking process in traveling-wave regime. The relations between the pulse parameters and the waveguide's properties are chosen in such a way that the mode-locking process is incoherent in behavior that leads to the phase decay of the incoming pulses. The analysis performed demonstrates that bright optical solitons can be supported by the waveguides with slowly saturable gain and fast relaxing saturable absorption.
