摘要
In this study, the operating conditions to obtain complete synchronization in two quantum cascade lasers with mutual optoelectronic coupling are analyzed. Synchronization properties and the effect of parameter mismatches on synchronization quality are investigated. The present simulation shows that the complete synchronization can be realized under suitable system parameters. The results of the present simulation indicate that the significant effects of coupling strength, photon lifetime and gain stages number on the synchronization quality. On the other hand, the present results indicate that the insignificant effect of the feedback delay time, the coupling delay time and the synchronization can occur at any delay-time conditions (DTCs).
