摘要
研究了由Lorenz-Haken方程所描述的混沌激光器阵列的动力学同步行为.通过对两个具有相同拓扑结构的复杂网络之间双向随机耦合的横向Lyapunov指数的计算,发现必须采用动力学对称耦合才能使得两个拓扑结构相同的非全同混沌激光器阵列中对应激光器达到同步,并成功地对双向随机耦合的两个复杂网络间对应激光器的动力学同步行为进行了数值仿真,证明该方法的可行性.
The dynamic synchronization of chaotic laser array described by the Lorenz-Haken equation has been studied.The transverse Lyapunov exponent of the two identical topological complex networks coupled with bidirectional random has been calculated.It is found that the dynamic symmetrical coupling can make the corresponding lasers in these two complex networks synchronized.The dynamic synchronization behavior of the two complex networks coupled with bidirectional random has been numerically simulated and the feasibility of this method has been proved.
