我们报告了利用超紧凑近场相互作用直接耦合等离子体和光子纳米线。在单个Ag和ZnO纳米线之间实现了高达80%的光子-等离子体激元耦合效率，耦合长度下降到200 nm的水平。混合纳米光子组件，包括偏振分束器，马赫-曾德尔干涉仪，和microwave腔，制造出耦合的银和ZnO纳米线。这些组件提供相对较低的损耗与亚波长限制;混合纳米线微腔表现出520的Q因子。
We report direct coupling of plasmonic and photonic nanowires using ultracompact near-field interaction. Photon-plasmon coupling efficiency up to 80% with coupling length down to the 200 nm level is achieved between individual Ag and ZnO nanowires. Hybrid nanophotonic components, including polarization splitters, Mach-Zehnder interferometers, and microring cavities, are fabricated out of coupled Ag and ZnO nanowires. These components offer relatively low loss with subwavelength confinement; a hybrid nanowire microcavity exhibits a Q-factor of 520.
