光子腔阵列是发展大规模光子集成电路和研究由于相互作用的纳米谐振器之间的光子跳跃而产生的基本量子电动力学现象的重要结构。在这里，我们通过扫描近场光谱、数值计算和分析模型，研究了不同邻近相互作用在不同光子晶体阵列结构中引起离域超模的作用。所研究的系统包括三个名义上相同的二维光子晶体纳米腔，它们沿三角形光子晶格的两个对称轴排列在薄膜上。我们发现最近邻和次近邻耦合项可以具有相同的关联性。在这种情况下，一幅非直观的图像描述了共振模式，相邻纳米谐振器之间的光子跳跃受到了强烈影响。我们的发现证明了奇异的配置，甚至是制造后的引擎..。
Arrays of photonic cavities are relevant structures for developing large-scale photonic integrated circuits and for investigating basic quantum electrodynamics phenomena due to the photon hopping between interacting nanoresonators. Here we investigate, by means of scanning near-field spectroscopy, numerical calculations and an analytical model, the role of different neighboring interactions that give rise to delocalized supermodes in different photonic crystal array configurations. The systems under investigation consist of three nominally identical two-dimensional photonic crystal nanocavities on membrane aligned along the two symmetry axes of the triangular photonic crystal lattice. We find that the nearest-neighbor and next-nearest-neighbor coupling terms can be of the same relevance. In this case, a nonintuitive picture describes the resonant modes, and the photon hopping between adjacent nanoresonators is strongly affected. Our findings prove that exotic configurations and even postfabrication engine...
