Optomechanical systems couple light stored inside an optical cavity to the motion of a mechanical mode. Recent experiments have demonstrated setups, such as photonic crystal structures, that in principle allow one to confine several optical and vibrational modes on a single chip. Here we start to investigate the collective nonlinear dynamics in arrays of coupled optomechanical cells. We show that such "optomechanical arrays" can display synchronization, and that they can be described by an effective Kuramoto-type model.
光机械系统将光存储在光学腔内，并将其与机械模式的运动耦合。最近的实验已经证明了一些设置，例如光子晶体结构，它们原则上允许在单个芯片上限制几个光学和振动模式。在这里，我们开始研究耦合光机械单元阵列的集体非线性动力学。我们表明，这种“光机械阵列”可以显示同步，并且可以用有效的 Kuramoto 型模型来描述。
