For the realization of quantum repeaters, coherent systems are essential. In the last decades, defects in diamond, especially the negatively charged silicon vacancy center (SiV−), drew attention due to exceptional optical properties. To overcome issues concerning low rates of spontaneous emitted photons, poor extraction efficiency out of the diamond material, as well as low quantum yield, coupling of the relevant optical dipole transition to the mode of a microcavity is one possibility.
We present a system, consisting of SiV− centers, located in a thin diamond membrane, coupled to a fiber based microcavity. We aim for enhanced spontaneous emission rates, due to the Purcell effect.
