Abstract

The single-atom Rabi splitting predicted a while ago [1,2] has recently been observed [3], and the double peaked structure expected from the theory verified. The origin of the vacuum Rabi splitting may may be considered to be due to transitions involving the lowest Autler-Townes doublet of the dressed atom energy level structure. Here we consider a two-level atom in the cavity environment, and calculate numerically the modifications to the emission spectrum produced when a broadband squeezed vacuum is allowed to interact with the system. The advantage of the cavity environment as compared to free space is that the squeezed field does not have to occupy all 4π modes of space, thus simplifying the experimental test of these predictions. The squeezed field need occupy only a relatively small solid angle. Here, however, we assume the one dimensional situation. We show that even a very small intensity of the squeezed vacuum can profoundly affect the spectrum.
