Quantum network nodes are an essential building block to realize a Quantum Internet [1]. Color centers in diamond, like the established Nitrogen-Vacancy (NV) with its long spin coherence and spin register capabilities or the emerging Tin-Vacancy (SnV) centers, are promising candidates to realize such quantum nodes [2 ]. Integrating the color center into an open microcavity and therefore boosting the emission of coherent photons via the Purcell effect can significantly improve the entanglement rate of the system [3, 4]. Here we present a fabrication method for the required µm-thin color center enriched diamond platelets bonded to a Bragg mirror as well as the characterization of those samples in terms of emitter properties and performance in an open microcavity [5].
