我们报道了两个耦合光子晶体纳米腔的远场测量。反对称模(零发射角处的强度极小值)的明显特征使我们能够展示腔场之间的pi位相差，这是一个明显的逝去耦合的特征。实验结果与模拟的辐射方向图符合得很好。(C)2011年美国物理研究所。[DOI：10.1063/1.3633106]
We report on far field measurements on two coupled photonic crystal nanocavities. The distinct features of the antisymmetric modes (minima of intensity at zero-emission angles) allow us to demonstrate a pi-phase difference between the cavity fields, a clear signature of evanescent coupling. Good agreement between experimental results and simulated radiation patterns has been found. (C) 2011 American Institute of Physics. [doi:10.1063/1.3633106]
