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.
