Abstract
The results of studying quasi-stationary optical pulses in single-mode semiconductor laser waveguides, being periodically domained in a direction of passing the waves, are presented. Steady states of the issuing optical pulses 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 waveguides' 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 the sequences of pulses and bright or dark optical solitons can be supported by such waveguide structures with a quasi-linear gain and a fast-relaxing saturable absorption. Reaching the steady state in pulse parameters is described in terms of the diffusive instability.
