Abstract
We experimentally investigate the evolutions of the chaotic characteristics in semiconductor laser subjected to microring resonator combined with optical injection. When the experimental parameters are changed, we calculate the standard bandwidth, flatness, and time-delay signature value of the chaotic laser. By the multiple beam interference effect, linear filtering effect and nonlinear self-phase modulation effect of microring resonator, as well as the beating frequency effect of optical injection, a chaotic laser with the standard bandwidth of 33.9 GHz, the flatness of ±3.7 dB, and the time-delay signature value of 0.08 is generated. Furthermore, the maps of the bandwidth, flatness and time-delay signature value of chaotic laser in the parameter space of the injection strength and frequency detuning are obtained. The results show that the chaotic laser with the bandwidth greater than 25.0 GHz, the flatness lower than ±5.0 dB, and the time-delay signature value lower than 0.10 can be generated simultaneously in a wide range of operating parameters.
