标题： Whispering gallery mode hybridization in photonic molecules

摘要： 这项工作受到化学的启发，其中分子的光谱特性由从单个原子轨道演变而来的电子态的杂化决定。 基于量子力学与经典电动力学之间的类比，我们将介电微球的低声波模式（WGM）共振几乎相同的位置进行了分类。 使用这些微球作为经典的光子原子，我们将它们组装成包括线性链和二维光子分子在内的各种结构。 我们通过锥形微纤维侧耦合以及有限差分时域建模来研究这些结构中的WGM杂化效应。 我们证明了WGM光谱分裂的模式代表了光子分子的对称性、组成原子的数量和拓扑结构，这些在原则上可以被视为各种分子的“光谱特征”。 我们还展示了控制这种分子中WGM耦合常数的新方法。 测量的透射光谱与模拟预测的光子分子的光谱特征之间表现出良好的一致性。 显示英文摘要

摘要： This work takes inspiration from chemistry where the spectral characteristics of the molecules are determined by hybridization of electronic states evolving from the individual atomic orbitals. Based on analogy between quantum mechanics and the classical electrodynamics, we sorted dielectric microspheres with almost identical positions of their whispering gallery mode (WGM) resonances. Using these microspheres as classical photonic atoms, we assembled them in a wide range of structures including linear chains and planar photonic molecules. We studied WGM hybridization effects in such structures using side coupling by tapered microfibers as well as finite difference time domain modeling. We demonstrated that the patterns of WGM spectral splitting are representative of the symmetry, number of constituting atoms and topology of the photonic molecules which in principle can be viewed as "spectral signatures" of various molecules. We also show new ways of controlling WGM coupling constants in such molecules. Excellent agreement was found between measured transmission spectra and spectral signatures of photonic molecules predicted by simulation.
