我们描述了一种技术,该技术能够在光学频率下实现单个光学发射器与导电纳米结构中的引导等离子体激元激发之间的强相干耦合。我们表明,在现实条件下,光发射几乎可以完全直接进入等离子体激元模式。作为一个例子,我们描述了这种技术的应用,涉及有效的单光子产生的需求,其中等离子体有效地耦合到一个电介质波导。
We describe a technique that enables strong, coherent coupling between individual optical emitters and guided plasmon excitations in conducting nanostructures at optical frequencies. We show that under realistic conditions optical emission can be almost entirely directed into the plasmon modes. As an example, we describe an application of this technique involving efficient generation of single photons on demand, in which the plasmon is efficiently outcoupled to a dielectric waveguide.
