摘要: The spatial and temporal coherence of the fluorescence emission controlled by a quasi-two-dimensional hybrid photonic–plasmonic crystal structure covered with thin fluorescent-molecular-doped dielectric film is investigated experimentally. A simple theoretical model to describe how confined optical mode may induce coherent also presented. Concerning coherence, it experimentally observed that area in plane light source excess 49 μm2, which results enhanced directional emission. obtained time 4 times longer than normal vacuum. Moreover, Young's double-slit interference experiment performed directly confirm spatially This smoking gun proof reported here for first optical-mode-modified
