The combination of classical integrated photonic structures with color centers in diamond, like the Silicon Vacancy (SiV−) Center, offer a promising platform for on-chip quantum optics experiments. We functionalize classical silicon nitride photonic crystal cavities with SiV− color centers in nanodiamonds in a hybrid approach. We show the experimental results coupling SiV− centers efficiently to a photonic crystal cavity mode and the Purcell enhanced emission of individual SiV− transitions [1]. By utilizing two mode coupling we achieved lifetimes of 460 ps [2].
