Single photon emitters in a solid state environment are inevitably coupled to phonon modes of the host material. On the one hand, decoherence induced by this coupling is often detrimental for harnessing the full potential of such emitters. On the other hand, this interaction in principle allows for control of the emitter not only optically, but also acoustically. Hybrid systems, comprised of optical, acoustic and excitonic components thus offer a high degree of flexibility by making use of all available interaction channels.
We consider here a single photon emitter located inside a phononic resonator and driven by an external laser. We derive analytical expressions for the resonance fluorescence (RF) spectrum, depending explicitly on the quantum statistics of the resonator mode. We show that, in principle, the statistics of the phonon mode can be determined from a given RF spectrum using our analytical model. We thus establish a simple and direct connection between the optical and acoustic components of such a hybrid system, paving the way for using single photon emitters as quantum transducers between the optical and acoustic domain.
