在这项工作中，我们从理论上研究了两个光机耦合谐振器的混合系统，该系统表现出诱导透明度。这是通过将光学环形谐振器耦合到环形线圈来实现的。在半经典分析中，系统显示双稳定性、孤立分支（isolas）和自持振荡动力学。此外，我们发现诱导透明窗口敏感地依赖于机械运动。基于这一事实，我们证明所描述的系统可以用作弱力探测器，并且在可用的实验条件下，无需使用反馈控制或挤压，最佳灵敏度就可以超越标准量子极限。
In this work we theoretically investigate a hybrid system of two optomechanically coupled resonators, which exhibits induced transparency. This is realized by coupling an optical ring resonator to a toroid. In the semiclassical analyses, the system displays bistabilities, isolated branches (isolas), and self-sustained oscillation dynamics. Furthermore, we find that the induced transparency window sensitively relies on the mechanical motion. Based on this fact, we show that the described system can be used as a weak force detector and the optimal sensitivity can beat the standard quantum limit without using feedback control or squeezing under available experimental conditions.
