Indirect light-matter interaction in dissipative coupled cavities.

Abstract

We examine the dynamics of evolution for an ensemble of three-level Λ atoms localized in a coupled cavity. In this scheme, when many atoms interact with one of the cavities, we observe Rabi oscillations between an atom and the other cavity. We show strong coupling between the ensemble and cavity is not necessary. The effective coupling can be improved by increasing the number of atoms. When the amplitude of the classical field is not equal to the photon hopping rate, for zero detunings, we achieve resonance and observe oscillations. The excited state of the atoms in one cavity may be eliminated hence suppressing atomic spontaneous emissions with an increase in the number of atoms. The optimal process range of hopping rate and classical field amplitude are found to optimize performance for a given parametric condition.
