在纳米尺度上对光-物质相互作用的了解为许多未来的技术、应用和材料奠定了基础。本文的研究范围是由光子微腔和金属纳米结构组合而成的光子-等离子体耦合系统。在这样的系统中，可以观察到谐振器的电磁光模和金属中的集体电子振荡(等离子体)之间的极强耦合。此外，结果还表明，由于等离子体激元的激发相移依赖于环境，耦合的光子-等离子体激元结构比传统的局域等离子体激元传感器对环境变化具有相当高的灵敏度。
The understanding of light-matter interactions at the nanoscale lays the groundwork for many future technologies, applications and materials. The scope of this article is the investigation of coupled photonic-plasmonic systems consisting of a combination of photonic microcavities and metallic nano-structures. In such systems, it is possible to observe an exceptionally strong coupling between electromagnetic light modes of a resonator and collective electron oscillations (plasmons) in the metal. Furthermore, the results have shown that coupled photonic-plasmonic structures possess a considerably higher sensitivity to changes in their environment than conventional localized plasmon sensors due to a plasmon excitation phase shift that depends on the environment.
