Cryogenic platform for coupling color centers in diamond membranes to a fiberbased microcavity
Abstract
We operate a fiberbased cavity with an inserted diamond membrane containing ensembles of silicon vacancy centers (SiV-) at cryogenic temperatures ≥4~K. The setup, sample fabrication and spectroscopic characterization is described, together with a demonstration of the cavity influence by the Purcell effect. This paves the way towards solid state qubits coupled to optical interfaces as long-lived quantum memories.
