The coupling of color centers in diamond such as Nitrogen Vacancy (NV) and Silicon Vacancy (SiV) centers to microcavites is considered an essential building block for applications in quantum information technologies. We here report on the coupling of a single NV center to an all-fiber-cavity and show enhancement of emission into the cavity, making use of the emitters large phonon sideband [1]. Much larger enhancement is predicted for emitters with smaller linewidths, such as the SiV center, allowing efficient cavity coupling even at room temperature. We here present our progress towards open-access microcavities for SiV wavelengths and the production of SiV centers in nanodiamonds. [1]Appl. Phys. Lett. 105, 073113 (2014)
