The combination of classical integrated photonic structures with color centers in diamond, like the Nitrogen Vacancy (NV−) or the Silicon Vacancy (SiV−) Center, offer a promising platform for on-chip quantum optics experiments. We combine silicon nitride photonic crystal cavities with color centers in nanodiamonds in a hybrid approach. We show the experimental results coupling NV centers efficently to a photonic crystal cavity mode [1] and the purcell enhanced emission of individual SiV− centers in nanodiamonds with a Purcell factor of 4 [2]. In this poster we lay out the details of our experiments.
