The paper reports on the photon emission properties of ‘silicon-vacancy’ (SiV) color centers in nanodiamonds synthesized by High−Pressure High−Temperature (HPHT), integrated with a high-quality factor (Q > 10,000) Si3N4 ring  microresonator coupled to a waveguide. The feasibility of collecting SiV-emission through the waveguide is demonstrated, marking a crucial step towards the integration of quantum emitters in photonic circuits. Zero phonon line of  SiV-fluorescence, recorded from the waveguide under confocal laser excitation, revealed a full width at half maximum of ~0.3 nm, which is 19 times narrower than in case of free space linewidth, and a Q-factor of approximately 2,500.  In addition, efficient excitation of SiV-centers in nanodiamonds by laser pumping through the waveguide is demonstrated, underscoring the practicality of waveguide-coupled microresonators for on-chip quantum photonic  applications. Finally, perspectives and limitations of such a platform for integrated optics and quantum communication technologies is discussed.
