Abstract

This paper presents an open laser parallel synchronization network comprising double centers and two chains. The double centers consist of two coupled lasers, while n (n N) single lasers are used as n nodes installed in series in one chain and n single-injected lasers are used as n nodes installed in series in another chain. An external light is injected into each node's laser in one chain and a center's laser to enable the closed optical network to be developed into an open optical network. Our study demonstrates that chaos control of each node laser of the network can be achieved via external light injection, and network parallel synchronization can be obtained in two chains. We find the controlled quasi-periodic synchronization regions. When dynamic chaos control of the network is achieved by shifting the external light injection, the network obtains quasi-periodic parallel synchronization in two chains. We provide a bifurcation diagram of the closed network, a bifurcation diagram of the open network, and a bifurcation diagram varying with the external light injection, displaying routes to chaos after passing double-periodic bifurcation through four-period or quasi-period. We find that there are clear, different routes to chaos operated in the closed network and the open network and that external light injection can guide a route away from chaos, while chaos control is achieved in the open network. The results have important reference value for the study of the control and synchronization of optical networks, laser technology, complex systems, and chaos.
开放2n-D激光并行同步网络及其多态混沌控制
提出了一种由双中心双链组成的开放式激光平行同步网络。双中心由两个耦合激光器组成,其中n (n∈n)个单激光器作为n个节点串联安装在一条链上,n个单注入激光器作为n个节点串联安装在另一条链上。将外部光注入一条光链中每个节点的激光器和一个中心的激光器,使封闭光网络发展成为开放光网络。我们的研究表明,通过外部光注入可以实现网络各节点激光的混沌控制,并且可以在两条链上实现网络的并行同步。我们找到了受控的准周期同步区域。当通过转移外部光注入实现网络的动态混沌控制时,网络在两条链上实现准周期并行同步。我们给出了封闭网络的分岔图、开放网络的分岔图和随外部光注入变化的分岔图,显示了通过四周期或准周期双周期分岔后进入混沌的路径。我们发现,在封闭网络和开放网络中运行着清晰的、不同的混沌路径,外部光注入可以引导一条远离混沌的路径,而在开放网络中实现了混沌控制。研究结果对光网络的控制与同步、激光技术、复杂系统和混沌的研究具有重要的参考价值。

期刊介绍: Reviews in Physics is a gold open access Journal, publishing review papers on topics in all areas of (applied) physics. The journal provides a platform for researchers who wish to summarize a field of physics research and share this work as widely as possible. The published papers provide an overview of the main developments on a particular topic, with an emphasis on recent developments, and sketch an outlook on future developments. The journal focuses on short review papers (max 15 pages) and these are freely available after publication. All submitted manuscripts are fully peer-reviewed and after acceptance a publication fee is charged to cover all editorial, production, and archiving costs.
