Synchronization, the emergence of spontaneous order in coupled systems, is of fundamental importance in both physical and biological systems. We demonstrate the synchronization of two dissimilar silicon nitride micromechanical oscillators, that are spaced apart by a few hundred nanometers and are coupled through an optical cavity radiation field. The tunability of the optical coupling between the oscillators enables one to externally control the dynamics and switch between coupled and individual oscillation states. These results pave a path toward reconfigurable synchronized oscillator networks.
同步，即耦合系统中自发现象的出现，在物理和生物系统中都具有重要意义。我们展示了两个相隔数百纳米的不同氮化硅微机械振荡器的同步，它们通过光腔辐射场耦合。振荡器之间光耦合的可调谐性使得能够外部控制动力学并在耦合和独立振荡状态之间切换。这些结果为可重构的同步振荡器网络铺平了道路。
