Summary:
The nonlinear dynamics and chaos bandwidth of a three-section monolithically integrated semiconductor laser (MISL) subject to optical injection are investigated experimentally. The results show that, the solitary MISL can operate at various dynamical states by adjusting the currents of three sections, but the chaotic region is very small and the maximum chaos bandwidth is about 14GHz. After introducing an external optical injection, mappings of the dynamical states and the chaos bandwidth of the MISL in the parameter space of the injection strength and frequency detuning are presented. Under suitable injection parameters, the chaotic region can be greatly expanded, and the chaos bandwidth can reach more than 36GHz.
