金刚石中的氮空位（NV）缺陷中心最近成为量子光学和量子信息领域中许多应用的有希望的候选者，例如单光子产生和自旋量子比特操作。这些缺陷中心的性能可以通过与等离子体和光子纳米结构（如金属粒子和光学微腔）的耦合而得到增强。在这里，我们通过扫描近场探针的操作演示了这种混合结构的受控组装。特别地，我们研究了等离子体通过与金纳米球的耦合对单光子发射的增强，以及金刚石纳米晶体与微球谐振器和光子晶体腔的光学模式的耦合。这些系统代表了基本的纳米光子/等离子体元素的原型，并在单个量子发射器的水平上提供对光子产生和相干转移的控制。(c) 2009 Elsevier B.V.版权所有
Nitrogen-vacancy (NV) (NV) defect centers in diamond have recently emerged as promising candidates for a number of applications in the fields of quantum optics and quantum information, such as single photon generation and spin qubit operations. The performance of these defect centers can strongly be enhanced through coupling to plasmonic and photonic nanostructures, such as metal particles and optical microcavities. Here, we demonstrate the controlled assembly of such hybrid structures via manipulation with scanning near-field probes. In particular, we investigate the plasmonic enhancement of the single photon emission through coupling to gold nanospheres as well as the coupling of diamond nanocrystals to the optical modes of microsphere resonators and photonic crystal cavities. These systems represent prototypes of fundamental nanophotonic/plasmonic elements and provide control on the generation and coherent transfer of photons on the level of a single quantum emitter.
