AI 中文摘要
我们实验研究了在同时包含耗散和色散分量的复杂互耦合下的激光同步。利用可重构的数字简并腔激光器，并精确控制系统参数，我们表明复杂耦合可以诱导频率吸引和排斥，这与常见的耦合振荡器模型形成对比。此外，我们表明这些频率偏移可用于显著增强多激光器阵列中的全局同步。与数值和理论结果的比较表明，复杂耦合激光器的振幅动力学在观察到的现象中起着重要作用。我们的结果为在定制激光网络中探索非厄米物理和拓扑态建立了一个多功能平台。
英文摘要
We experimentally investigate laser synchronization under complex mutual coupling, featuring both dissipative and dispersive components. Using a reconfigurable digital degenerate cavity laser with precise control over system parameters, we show that complex coupling can induce both frequency attraction and repulsion, in contrast to common models of coupled oscillators. Furthermore, we show that these frequency shifts can be exploited to significantly enhance global synchronization in multi-laser arrays. Comparison with numerical and theoretical results indicate that amplitude dynamics of complex coupled lasers play an important role in the observed phenomena. Our results establish a versatile platform for exploring non-Hermitian physics and topological states in tailored laser networks.
