We demonstrate that ultrasmall double-layer photonic-crystal-slab cavities exhibit a very high-Q value for a wide range of the layer spacing, which enables us to realize unique optomechanical coupling. By mechanically varying the separation, we can achieve extraordinarily large wavelength conversion. In addition, the light stored in the cavity can generate a large radiation force. We show that this system exhibits extremely high energy conversion efficiency between optical and mechanical energy, leading to a novel approach for the optomechanical control of light and matter.
我们证明，超小双层光子晶体平板腔在很宽的层间距范围内都表现出非常高的品质因数，这使我们能够实现独特的光机械耦合。通过机械改变间距，我们可以实现极大的波长转换。此外，腔内存储的光可以产生很大的辐射力。我们表明，该系统在光能和机械能之间表现出极高的能量转换效率，从而产生了一种用于光和物质的光机械控制的新方法。
