# Complete conversion of the single photon frequency in an optical microcavity

@article{Sumetsky2018CompleteCO, title={Complete conversion of the single photon frequency in an optical microcavity}, author={Misha Sumetsky}, journal={arXiv: Optics}, year={2018} }

We describe an optical cavity resonantly coupled to N atoms which performs the complete conversion of the single photon frequency in the absence of external driving field. Two states of this cavity couple to two transitions between three atomic levels and two input-output waveguides. The problem is reduced to the consideration of coupled 2N+1 localized and N+1 waveguide collective states of a photon and atoms and solved exactly using the Mahaux-Weidenmuller formalism. The conditions of complete…

An investigation of the spectral response of a small collection of two-state atoms strongly coupled to the field of a high-finesse optical resonator finds a coupling-induced normal-mode splitting even for one intracavity atom, representing a direct spectroscopic measurement of the so-called vacuum Rabi splitting for the atom-cavity system.
