This paper presents a case study of a semiconductor laser with a saturable absorber (SLSA) and an external optical feedback loop. The system is modeled by the Yamada rate equations to which a feedback term has been added. Starting from the bifurcation analysis of the SLSA alone, the influence of feedback strength and delay time is investigated by means of a numerical bifurcation analysis. The emphasis is on excitable dynamics and self-sustained oscillations in the presence of the feedback loop.
