论文摘要
在这项工作中，我们研究了连续体在电信波长和高索引波长尺寸磁盘中的连续体的光学准式 - 机械模式下的色散耦合。我们表明，这样的空腔可以与光学机械晶体腔（$ g_ {0}/2π\ BackSimeq $ 800 kHz）显示出光学耦合速率的值。有趣的是，在频率高于10 GHz的频率的光学共振与机械模式之间的光学机械耦合似乎可以实现。我们还表明，通过将磁盘放在薄的二氧化硅基座上，可以极大地降低基材中的机械泄漏。我们的结果表明，超紧凑的光力腔的新途径可能会在形成光学机械跨面的大规模阵列中排列。
In this work, we study the dispersive coupling between optical quasi-bound-states in the continuum at telecom wavelengths and GHz-mechanical modes in high-index wavelength-sized disks. We show that such cavities can display values of the optomechanical coupling rate on par with optomechanical crystal cavities ($g_{0}/2π\backsimeq$ 800 kHz). Interestingly, optomechanical coupling of optical resonances with mechanical modes at frequencies well above 10 GHz seems attainable. We also show that mechanical leakage in the substrate can be extremely reduced by placing the disk over a thin silica pedestal. Our results suggest a new route for ultra compact optomechanical cavities which can potentially be arranged in massive arrays forming optomechanical metasurfaces.
