在许多动态系统和复杂网络中，时滞自然地出现在反馈回路或单个元件的耦合连接中。此外，在整个系统类别中，这些延迟时间可能依赖于系统的状态。然而，到目前为止，对这种依赖于国家的延迟的影响的理解仍然很差，特别是缺乏系统的实验研究。在这里，我们通过引入一个概念上简单的光子系统来填补这一空白，该系统表现出根据系统状态在两个具有两种不同延迟时间的环路之间自组织切换的动力学。在采用频率选择反馈镜的半导体激光器的实验和建模的基础上，我们描述了由单个延迟定义的状态之间的切换。我们的方法为这类动力系统的研究开辟了新的视角，并使自组织开关的应用得以利用。动态系统和复杂网络中反馈回路和连接的时间延迟可能取决于系统的状态，但人们对这些状态相关的延迟知之甚少。在这里，作者使用光子系统来表征具有不同延迟时间的两个环路之间的切换。
In many dynamical systems and complex networks time delays appear naturally in feedback loops or coupling connections of individual elements. Moreover, in a whole class of systems, these delay times can depend on the state of the system. Nevertheless, so far the understanding of the impact of such state-dependent delays remains poor with a particular lack of systematic experimental studies. Here we fill this gap by introducing a conceptually simple photonic system that exhibits dynamics of self-organised switching between two loops with two different delay times, depending on the state of the system. On the basis of experiments and modelling on semiconductor lasers with frequency-selective feedback mirrors, we characterize the switching between the states defined by the individual delays. Our approach opens new perspectives for the study of this class of dynamical systems and enables applications in which the self-organized switching can be exploited. Time delays in feedback loops and connections in dynamical systems and complex networks can depend on the state of the system, but these state-dependent delays are poorly understood. Here, the authors use a photonic system to characterize the switching between two loops with different delay times.
