Abstract

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 field enhancement and high quality factor (Q approximately 900) opens new routes for the control of light-matter interaction at the nanoscale.

摘要

我们提出并演示了一种混合腔系统，其中金属纳米粒子通过纳米组装方法与介电光子晶体腔倏逝耦合。虽然金属成分导致了强烈的局域场，但光学反馈是由周围的光子晶体结构提供的。等离子体场增强和高品质因数（Q 约为 900）的综合效应为控制纳米尺度的光物质相互作用开辟了新途径。
