Abstract

We demonstrate the influence of vectorial coupling on the synchronization behavior of complex systems. We study two semiconductor lasers subject to delayed optical feedback which are unidirectionally coherently coupled via their optical fields. Our experimental and numerical results demonstrate a characteristic synchronization scenario in dependence on the relative feedback phase leading cyclically from chaos synchronization to almost uncorrelated states, and back to chaos synchronization. Finally, we reveal the influence of the feedback phase on the dynamics of the solitary delay system.

摘要

我们展示了矢量耦合对复杂系统同步行为的影响。我们研究了两个受到延迟光反馈的半导体激光器，它们通过光场进行单向相干耦合。我们的实验和数值结果表明，根据相对反馈相位会出现一种特征性的同步情况，周期性地从混沌同步转变为几乎不相关的状态，然后再回到混沌同步。最后，我们揭示了反馈相位对孤立延迟系统动力学的影响。
