实验研究了由覆盖有荧光分子掺杂的电介质薄膜的准二维光子-等离子体混合晶体结构控制的荧光发射的空间和时间相干性。一个简单的理论模型来描述如何限制准二维光学模式可以诱导相干荧光发射。在空间相干性方面，实验观察到光源平面内的相干面积超过49 μm2，从而增强了定向荧光发射。在时间相干性方面，所获得的相干时间比真空中正常荧光发射的相干时间长4倍。此外，杨氏双缝干涉实验进行直接确认的空间相干发射。本文首次报道了光模修正发射的空间相干性的确凿证据。
The spatial and temporal coherence of the fluorescence emission controlled by a quasi-two-dimensional hybrid photonic–plasmonic crystal structure covered with a thin fluorescent-molecular-doped dielectric film is investigated experimentally. A simple theoretical model to describe how a confined quasi-two-dimensional optical mode may induce coherent fluorescence emission is also presented. Concerning the spatial coherence, it is experimentally observed that the coherence area in the plane of the light source is in excess of 49 μm2, which results in enhanced directional fluorescence emission. Concerning temporal coherence, the obtained coherence time is 4 times longer than that of the normal fluorescence emission in vacuum. Moreover, a Young's double-slit interference experiment is performed to directly confirm the spatially coherent emission. This smoking gun proof of spatial coherence is reported here for the first time for the optical-mode-modified emission.
