Chaos synchronization of coupled nano-quantum cascade lasers with negative optoelectronic feedback

摘要: In this paper, a theoretical investigation of chaos synchronization in two nano-quantum cascade lasers with delayed negative optoelectronic feedback is presented. Since the spontaneous emission effect an important factor microcavity rate equations model has been reconsidered to include Purcell enhancement F and factor. It found that takes place under suitable system parameters. The results indicate coupling strength, delay time transmitter, transmission between have significant effects on quality while stage number receiver poor quality. Also, when closed-loop or open-loop, dynamics occurs small happens open-loop only large. Furthermore, closed-loop, large any values for
