光电反馈混沌系统脉冲同步特性研究

Chaotic impulse synchronization of opto-electronic feedback

提出光电反馈混沌状态下的混沌脉冲同步.首先,对激光器的混沌动力学方程进行了数值分析,通过改变反馈系数和脉冲系数来观测混沌状态的变化,实现了对混沌激光器的控制;然后,对脉冲同步方程进行数值分析,给出了同步的模拟图.实验结果表明此方法能实现混沌同步.

In this paper, a chaotic impulse synchronization is proposed by using opti-electronic feedback. The laser chaos dynamical equa- tions are numerically calculated, and the different chaotic states are obserred by modulating the coefficient of feedback or impulse which realizes the control of chaotic dynamics. Then, the impulse synchronization equations are numerically calculated, and the simulation image of synchronization is plotted. Experiments show the scheme can achieve the chaotic synchronization.
