Classical photonic platforms combined with quantum emitters, like the NV and the SiV center in diamond, enable for efficient quantum photonic devices. In a hybrid approach, we combine the SiV center in nanodiamonds with an efficient on-chip Photonic Crystal Cavity based on a Si3N4 photonic platform [1]. Utilizing an atomic force microscope, we developed a routine for placing and optimization of the emitter inside the mode of the cavity. For individual optical transitions of a single SiV center we achieved a Purcell enhancement of more than 4 [2].
