电耦合混沌激光中的关联

Correlations in Electrically Coupled Chaotic Lasers

E. J. Rosero, W. A. S. Barbosa, J. F. Martinez Avila, A. Z. Khoury, J. R. Rios Leite

摘要:

我们展示了如何两个电耦合的半导体激光器具有光反馈可以同时呈现反相相关的快速功率波动,和强的同步尖峰的混沌功率下降。实验证明了这种非常违反直觉的现象,并通过速率方程的确定性动力学系统的数值解证实了这一点。正如我们简单的安排所证明的那样,复杂系统各部分之间根据时间尺度发生的负相关和正相关,与复杂网络中集体性质的理解和表征有关。

英文摘要:

We show how two electrically coupled semiconductor lasers having optical feedback can present simultaneous anti-phase correlated fast power fluctuations, and strong in-phase synchronized spikes of chaotic power drops. This quite counter intuitive phenomenon is demonstrated experimentally and confirmed by numerical solutions of a deterministic dynamical system of rate equations. The occurrence of negative and positive cross correlation between parts of a complex system according to time scales, as proved in our simple arrangement, is relevant for the understanding and characterization of collective properties in complex networks.
