摘　　要：以三边三层多边形网络结构为出发点,建立互耦合半导体激光器的多边形网络结构模型,首先分析和研究了三边三层多边形网络结构中激光器的混沌同步特性。进而将三边三层多边形网络结构拓展到六边三层多边形网络结构甚至更为复杂的多边形网络结构,并以第一层的激光器为顶点激光器进行结构优化,研究了其结构中异层激光器之间的混沌同步。结果表明以三边三层多边形网络结构为基础,当增加多边形网络结构中边数,形成六边三层多边形网络结构甚至更为复杂的多边形网络结构时,除顶点激光器外的其他激光器仍能实现同层和异层混沌同步。Based on three-layer triangle network,the polygonal networks are established for mutually coupled semiconductor lasers.Firstly,the chaotic synchronization characteristics of the lasers in the three-layer triangle network are numerically analyzed and investigated.Then,the three-layer triangle network is extended to three-layer hexagonal network or even more complex polygonal network,and taking the first layer laser as the vertex laser for structural optimization,the proprieties of chaotic synchronization are studied between lasers in different layers for these complex structures.The results show that the lasers in three-layer triangle network,as well as in the three-layer hexagonal network or even more complex polygonal network formed by increasing side numbers of polygonal network,lasers except the apex can achieve chaotic synchronization in the same or different layers.
