VACUUM RABI SPLITTING OF AN ATOM DIPOLE NEAR A DIELECTRIC MICROSPHERE

A solution is found of the dispersion equation for a classical oscilla tor in the vicinity of a dielectric microsphere in the case of strong electromagnetic coupling. The solution obtained agrees with the corres ponding quantum-mechanical solution obtained within the framework of t he dressed states approach and presents a clear signature of the vacuu m Rabi splitting of the energy levels in real systems. Based on this s olution, a qualitative expression is found for the intensity of the re sultant line doublet.
