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

本提案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，并且具有迄今为止未实现的精度和灵活性。我们将使用在可见光范围内（~550 -800 nm）工作的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器的单个纳米颗粒（例如，金刚石纳米颗粒中的缺陷中心）将通过使用纳米操纵技术以确定的方式耦合到这些空腔中。这项技术利用原子力显微镜的悬臂尖端在纳米尺度上操纵粒子，使我们能够创造一个定制的光学环境，在这个环境中，发射器和空腔可以以一种良好的方式排列。因此，量子电动力学现象不仅可以在单发射体/单腔系统中研究，也可以在多发射体和多腔系统中研究。

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.
