ANOMALOUS RESONANCE FLUORESCENCE AND DRESSED-STATE INVERSION BY SQUEEZED-LIGHT IN A FABRY-PEROT MICROCAVITY

It has been suggested that phased atomic decay in a squeezed vacuum co uld be detected in the fluorescence spectrum emitted from a driven two -level atom in a cavity. Recently, the existence of other very distinc tive features in the fluorescence spectra arising from the nonclassica l features of the squeezed vacuum has been reported. In this paper, we investigate the possibility of experimental observation of these spec tra. The main obstacle to the experimentalist is ensuring an effective squeezed-vacuum-atom coupling. To overcome this problem we propose th e use of a Fabry-Perot microcavity. The analysis involves a considerat ion of the three-dimensional nature of the electromagnetic held, and t he possibility of a mismatch between the squeezed and cavity modes. Th e problem of squeezing bandwidths is also addressed. We show that unde r experimentally realistic circumstances many of the spectral anomalie s predicted in free space also occur in this environment. In addition, we report large population inversions in the dressed states of the tw o-level atom. [S1050-2947(98)02301-4].
