We discuss a compact QED system of Germanium Vacancy(GeV) centres coupled to high quality factor silicon nitride nanobeam Photonic crystal(PhC) cavities. Devices with a quality factor of 24,000 around the zero-phonon line of the GeV center in diamond are demonstrated with an efficient fiber-to-waveguide coupling platform. We also present a method for fiber-waveguide coupling that allows seamless transition of photons from optical fibers into photonics devices and vice versa. Our method uses conical tapered optical fibers (with a tapering angle of ∼ 4° ) that are coupled over ∼ 11μm to a silicon nitride (Si3N4) waveguide taper (with a tapering angle of ∼ 1° ) achieving upto ∼ 96% coupling efficiency.
