Shaping the steady states of picosecond optical pulses in dissipative soliton regime by fast-relaxing multilayer semiconductor laser structures

摘要

The results of studying the steady states for bright and dark dissipative optical solitons, appearing in single-mode semiconductor laser structure multilayered in a direction of passing the waves, are presented. These types of solitons occur 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 structures' 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 demonstrates that both bright asymmetrical and dark (or flashing) dissipative optical solitons can be supported by such structure with a weakly illocal slowly saturable gain and a fast-relaxing saturable absorption.
