Tailored Light-Matter Coupling with Photonic Crystal Cavities in the Visible

这一提议的目标是实现一个纳米光子系统，在这个系统中，我们可以控制和研究光与物质的耦合，并且具有到目前为止还没有达到的精度和灵活性。我们将使用工作在可见光谱范围(~550-800 nm)的SiN光子晶体腔作为控制电磁环境的平台。包含单个或多个发射体(例如，钻石纳米颗粒中的缺陷中心)的单个纳米颗粒将通过使用纳米操纵技术以确定的方式耦合到这些空腔。这项技术利用原子力显微镜的悬臂尖端来操纵纳米级的粒子，并允许我们创建一个量身定做的光学环境，其中发射器和腔可以以良好的方式布置。因此，不仅可以在单发射体/单腔系统中研究量子电动力学现象，而且可以在具有多个发射体和腔体的系统中研究量子电动力学现象。

The goal of this proposal is the realization of a nanophotonic system in which we can control and investigate the coupling of light and matter with so far unachieved precision and flexibility. We will use SiN photonic crystal cavities operating in the visible range of the spectrum ( ~550 -800 nm) as a platform to control the electromagnetic environment. Individual nanoparticles containing single or several emitters (e.g., defect centers in diamond nanoparticles) will be coupled to these cavities in a deterministic way by using a nanomanipulation technique. This technique utilizes the cantilever tip of an atomic force microscope to manipulate particles at the nanoscale and allows us to create a tailored optical environment, where emitters and cavities can be arranged in a well-de_ned manner. Thus, quantum electrodynamic phenomena can not only be studied in a single emitter/single cavity system, but also in a system with multiple emitters and cavities.
