Fabrication and characterization of Fabry-Pérot microcavities — •Felix Glöckler, Andrea Kurz, Andreas Dietrich, Fedor Jelezko, and Alexander Kubanek — University Ulm, Institute for Quantum Optics, Germany
Starting with the question whether the excited-state lifetime of an atom can be modified, many experiments have been performed in order to engineer the properties of quantum emitters. The change of spontaneous emission is typically associated with Purcell*s prediction that the radiation of a dipolar transition can be accelerated with a cavity by the Purcell factor FP=3 λ3/4 π2Q/V which is mainly dependent on the quality factor Q and the Volume V of the cavity. Realizing high Purcell factors via the recipe high Q low V is non-trivial. Open Fabry-Pérot cavities are particularly attractive to achieve this goal since they are easily tunable and compatible with different kinds of emitters. In this work we will concentrate on achieving sizable FP by optimizing the Q/V ratio.
