Dissipative Kerr soliton (DKS) frequency combs, when generated within coupled cavities, exhibit exceptional performance concerning controlled initiation and power conversion efficiency. Nevertheless, to fully exploit these enhanced capabilities, it is necessary to maintain the frequency comb in a low-noise state over an extended duration. In this study, we demonstrate the control and stabilization of super-efficient microcombs in a photonic molecule. Our findings demonstrate that there is a direct relation between effective detuning and soliton power, allowing the latter to be used as a setpoint in a feedback control loop. Employing this method, we achieve the stabilization of a highly efficient microcomb indefinitely, paving the way for its practical deployment in optical communications and dual-comb spectroscopy applications.

光子分子中超高效微梳的主动反馈稳定

当耗散克尔孤子（DKS）频率梳在耦合腔内产生时，在受控启动和功率转换效率方面表现出卓越的性能。然而，为了充分利用这些增强的功能，有必要在较长的时间内将频率梳保持在低噪声状态。在这项研究中，我们展示了光子分子中超高效微梳的控制和稳定。我们的研究结果表明，有效失谐和孤子功率之间存在直接关系，使得后者可以用作反馈控制环路中的设定点。利用这种方法，我们实现了高效微梳的无限稳定，为其在光通信和双梳光谱应用中的实际部署铺平了道路。
