同步的现象在整个自然科学中普遍发生，并为耦合非线性动力学系统的行为提供了重要的见解。它还提供了一种强大的方法，可以在包括通信，超导体和光子学在内的不同应用中进行稳健的频率或时间锁定。在这里，我们报告了两个耦合的孤子模式锁定的基于芯片芯片梳子的实验同步，在20 m的距离上分开。我们表明，这样的系统遵守通用的库拉莫托模型以进行同步，并且可以将微孔子的腔孤子连贯地组合在一起，从而克服了基于微孔孔的梳子的基本功率极限。这项研究可以显着扩大微孔梳子的应用，并具有大规模整合的能力，它为探索复杂的非线性系统提供了基于芯片的光子平台。
The phenomenon of synchronization occurs universally across the natural sciences and provides critical insight into the behaviour of coupled nonlinear dynamical systems. It also offers a powerful approach to robust frequency or temporal locking in diverse applications including communications, superconductors and photonics. Here, we report the experimental synchronization of two coupled soliton mode-locked chip-based frequency combs separated over distances of 20 m. We show that such a system obeys the universal Kuramoto model for synchronization and that the cavity solitons from the microresonators can be coherently combined, which overcomes the fundamental power limit of microresonator-based combs. This study could significantly expand the applications of microresonator combs, and with its capability for massive integration it offers a chip-based photonic platform for exploring complex nonlinear systems.
