Nanophotonic quantum devices can be used to significantly enhance the light-matter interactions required for applications such as quantum networks. Combining solid-state emitters exhibiting desirable optical and spin properties with scalable photonic devices remains a challenge.[1] Recently, hybrid approaches with the goal of scalable fabrication have been developed. [2,3]

Here we present our hybrid approach that combines negatively charged silicon vacancy centers in nanodiamonds with silicon nitride photonics. We utilize coherent Rabi oscillations to probe the local field strength. By adjusting the position and rotation of the emitter relative to the cavity using AFM-based nanomanipulation, we can control the coupling strength. This paves the way to deterministic coupling of preselected emitter to a cavity with the required properties.
