Bifurcation diagrams of the integrated mutual-injection semiconductor laser

The nonlinear dynamical characteristics of an integrated mutual-injection semiconductor laser (IMSL) with three-section are numerically simulated, and Hopf bifurcation diagrams of its output characteristics varying with different input parameters are presented. The simulation results in this paper indicate that by varying some operating parameters such as coupling strength and detuning frequency of an IMSL, its output exhibits rich nonlinear dynamical behaviors such as injection locking, period-one oscillations, period-two oscillations, multi-period oscillations, quasi-period oscillations, and chaos oscillations. In this paper, we explore the effect of parameter changes of IMSL on its output characteristics, numerically simulate these phenomena and reflect in the Hopf bifurcation diagram.
