英文摘要： Delay-coupled vertical cavity surface emitting lasers (VCSELs) have many properties, such as low threshold current, large modulation bandwidth, easy integration, easily coupled with optical fiber, unique dynamic behaviors, complex phenomena in photonics. By using these properties, the applications of the chaotic synchronization of delay-coupled VCSEL network expand some new fields that rang from complex secure communications network with multi channel and multi link, and photonic information processing to neural network. Therefor, it is an important task that the chaotic synchronization properties of delay-coupled VCSEL network are explored, as well as the new method and novel technique of the robust chaotic synchronization with zero-lag are obtained. This project aims to ascertain the internal laws of the chaotic properties of the node laser in the network composed of three node VCSELs. Moreover, the optimal scheme of asymptotic synchronization of chaos will be explored in global-coupled network. And the method for the optimal zero-lag chaos synchronization between two node lasers with unidirectional or bidirectional coupling can be obtained in each kind of network topology. Also it aims to master the key techniques of the control of chaotic synchronization with high quality and strong robustness in delay-coupled VCSELs network. In this project, based on small delay-coupled VCSEL network, it is hopeful that the chaos-synchronized secure communication system with confidentiality and high safety is performed. It is expected that the research of this project can provide some of the key technical support for promotion of the chaotic secure communication system with laser network into practicability.
