摘要: 研究在超混沌信号调制参数作用下简并光学参量振荡器的混沌同步.计算结果表明,当调制系数在某确定的范围内使系统的最大条件李指数为负数时,两个或更多台简并光学参量振荡器在新的动力学基础上可实现同步或倒同步.同步方式与初始条件和调制系数有关.当初始条件确定的情况下,调制系数取某些值时,系统的同步方式具有突变性.

Abstract: We study chaotic synchronization in degenerate optical parametric oscillators(DOPOs) by hyperchaotic signal modulating parameter.It shows that synchronization or inversed synchronization is realized in two or more chaotic systems by adjusting modulating coefficient as the maximum condition Lyapunov exponent(MCLE) of the system is negative.It is observed that the synchronization states depend on initial conditions and modulating coefficients.Under certain initial conditions,the synchronization state shows spontaneous mutation at some modulating coefficients.

Key words: optical chaos, modulating parameter, synchronization, degenerate optical parametric oscillators
