对微腔的光学模谱进行了修正，引入了横向光子限制，这是通过对谐振腔进行图案化来实现的。例如，通过调整谐振器的尺寸，实现了具有三维光子限制的系统。通过组装这些谐振器，得到了类似光子晶体的能带结构。修正后的模谱对于定制光-物质相互作用是有意义的，这通过两个例子得到证明：对于嵌入在这样的腔中的量子点，显示了对自发辐射的增强和抑制。修改后的模谱还允许定制弹性极化激元对散射。
The optical mode spectrum of microcavities is modified by introducing lateral photon confinement, which is achieved through patterning the resonator. By adjusting the resonator dimensions for example, systems with three-dimensional photon confinement are realized. By assembling these resonators, photonic crystal-like band structures are obtained. The modified mode spectrum is of interest for tailoring light-matter interactions, which is demonstrated by two examples: for quantum dots embedded in such cavities, an enhancement as well as suppression of the spontaneous emission is shown. The modified mode spectrum also allows for tailoring elastic polariton pair scattering.
