我们提出并演示了一种“自下而上”的方法来构建用于光子操纵的光子结构。采用超单分散聚合物微球作为构建块，采用光谱分析方法对微球进行分选，可以得到大于0.05%的尺寸均匀度。这些球位于硅衬底上的V型槽中，形成光学链，与光学回音廊模式共振耦合。在荧光光谱和共振散射光谱中观察到明显的光子带模式，并与紧束缚模型计算得到了很好的一致。获得了高达40的重光子态和群指数。
We propose and demonstrate a "bottom-up" approach to constructing photonic structures for photon manipulation. Supermonodispersive polymer microspheres are used as building blocks and a size uniformity better than 0.05% could be obtained by sorting the spheres using spectroscopic methods. The spheres are positioned in a V groove on a silicon substrate and form a photonic chain with resonant coupling of the optical whispering-gallery modes. Photonic band modes are clearly observed in fluorescence and resonant scattering spectra, and an excellent agreement with a tight-binding model calculation is found. Heavy photon states and a group index as high as 40 are obtained.
