Light scattering at an NV center in an optical cavity — •Ralf Betzholz, Marc Bienert, and Giovanna Morigi — Universität des Saarlandes, Saarbrücken, Germany

We study a system consisting of a single nitrogen-vacancy (NV) center in diamond situated in an optical resonator. In particular we investigate the light scattering at such a system when it is weakly driven by a laser. Since the NV center is embedded in a diamond crystal the interaction of the electronic degree of freedom to bulk phonons has to be taken into account in the description. Starting from a master equation approach we present absorption spectra as well as spectra of the NV centers fluorescence and the cavity output. By means of these spectra we discuss the influence of the coupling to bulk phonons on the light scattering at the composite system. Moreover, we investigate how the cavity parameters modify the spectral properties of the emitted light by comparison to the free space emission of an NV center.
