In recent years, optical chaos as a new research hotspot has attracted extensive attention. In order to improve the performance of chaos-based applications, we need to study the numerical value of its output chaotic signal.. In this contribution, the effects of injection parameters, i.e. the frequency detuning and injection strength, on time-delay signature (TDS) concealment and bandwidth enhancement of the three cascade-coupled semiconductor ring lasers (SRLs) are numerically investigated. The results show that, under the proper conditions, both the TDS elimination and bandwidth enhancement can be reached in the third SRL of cascade-coupled system.
