光与纳米结构材料的相互作用为研究量子现象的经典波类比提供了令人兴奋的新机会。一个特别令人感兴趣的主题是系统中波物理学和混沌之间的相互作用，在系统中，一个小的扰动可以将行为从经典状态驱动到混沌状态。在这里，我们报告了硅光子平台上的集成芯片中全光学激光驱动的从有序到混沌的转变。通过紫外线范围内超快激光脉冲引起的扰动，将电信波长的方形光子晶体微腔从有序状态调整为混沌状态。近红外弱探测脉冲的混沌动力学特征是针对不同的泵浦探测延迟时间和腔内的不同位置，具有高空间精度。我们的实验分析通过基于随机矩阵的数值建模得到证实，表明非线性光学可用于可逆地控制光学谐振器中光的混沌行为。
The interaction of light with nanostructured materials provides exciting new opportunities for investigating classical wave analogies of quantum phenomena. A topic of particular interest forms the interplay between wave physics and chaos in systems where a small perturbation can drive the behavior from the classical to chaotic regime. Here, we report an all‐optical laser‐driven transition from order to chaos in integrated chips on a silicon photonics platform. A square photonic crystal microcavity at telecom wavelengths is tuned from an ordered into a chaotic regime through a perturbation induced by ultrafast laser pulses in the ultraviolet range. The chaotic dynamics of weak probe pulses in the near infrared is characterized for different pump‐probe delay times and at various positions in the cavity, with high spatial accuracy. Our experimental analysis, confirmed by numerical modelling based on random matrices, demonstrates that nonlinear optics can be used to control reversibly the chaotic behavior of light in optical resonators.
