单量子激发态与银纳米线的耦合

Coupling of a Single Quantum Emitter to End-to-end Aligned Silver Nanowires

Shailesh Kumar, Alexander Huck, Yuntian Chen, Ulrik L. Andersen

摘要:

我们报告的观察耦合一个单一的氮空位(NV)中心的纳米金刚石晶体的银纳米线的传播等离子体模式。将银纳米线放置在单个银纳米线的顶点附近或两个端对端对齐的银纳米线之间的间隙中。我们观察到增强的NV中心的衰减率在这两种情况下,作为耦合到等离子体激元的结果。这些器件是用扫描探针技术纳米组装的。通过模拟,我们表明,端到端对齐的银纳米线可以用作可控的分裂器从偶极发射器的发射。

英文摘要:

We report on the observation of coupling a single nitrogen vacancy (NV) center in a nanodiamond crystal to a propagating plasmonic mode of silver nanowires. The nanocrystal is placed either near to the apex of a single silver nanowire or in the gap between two end-to-end aligned silver nanowires. We observe an enhancement of the NV-centers' decay rate in both cases as a result of the coupling to the plasmons. The devices are nano-assembled with a scanning probe technique. Through simulations, we show that end-to-end aligned silver nanowires can be used as a controllable splitter for emission from a dipole emitter.
