标题： `Deterministic' quantum plasmonics

摘要： 我们演示了在金等离激元接收器上自由选择位置的传播量子表面等离子体极化子的“确定性”激发。 这是通过使用由一个具有两个氮空位色心占据的金刚石纳米晶体作为等离激元发射器来实现的。 我们的演示依赖于薄而均匀的金膜的泄漏辐射显微镜和厚金膜的近场光学显微镜。 我们的工作为未来在需要单等离激元源精确定位的量子等离激元领域的基础研究和应用铺平了道路，并可能在等离激元学和纳米光子学中开辟一个新的分支，即扫描量子等离激元学。 显示英文摘要

摘要： We demonstrate `deterministic' launching of propagative quantum surface-plasmon polaritons at freely chosen positions on gold plasmonic receptacles. This is achieved by using as plasmon launcher a near-field scanning optical source made of a diamond nanocrystal with two Nitrogen-Vacancy color-center occupancy. Our demonstration relies on leakage-radiation microscopy of a thin homogeneous gold film and on near-field optical microscopy of a nanostructured thick gold film. Our work paves the way to future fundamental studies and applications in quantum plasmonics that require an accurate positioning of single-plasmon sources and may open a new branch in plasmonics and nanophotonics, namely scanning quantum plasmonics.
