我们提出并演示了一个混合腔系统，其中金属纳米粒子的倏逝耦合到一个电介质光子晶体腔使用纳米组装方法，而金属成分导致强烈的本地化领域，光反馈提供周围的光子晶体结构。等离子体增强和高品质因子（Q接近900）的综合效应为在纳米尺度上控制光-物质相互作用开辟了新的途径。
We propose and demonstrate a hybrid cavity system in which metal nanoparticles are evanescently coupled to a dielectric photonic crystal cavity using a nanoassembly method, While the metal constituents lead to strongly localized fields, optical feedback is provided by the surrounding photonic crystal structure. The combined effect of plasmonic held enhancement and high quality factor (Q approximate to 900) opens new routes for the control of light-matter interaction at the nanoscale.
