Abstract

Since the generation of squeezed light has become possible, interest has turned to possible applications and the effects of squeezed light on optical systems. Gardiner¹ and Carmichael, Lane, and Walls² have considered the effects of an atom which is immersed in squeezed light. It was found that the Lorentzian lineshape became a sum of two Lorentzians, one which narrowed as the amount of squeezing was increased, and another which broadened. It was recognized by these authors and others that it was impossible to squeeze all of the modes of the radiation field that the atom interacted with, and that an optical cavity would be needed. There have been a number of papers dealing with such a situation. Recently Xiao and Jin³ proposed placing two- level atoms inside an optical parametric oscillator, as the light inside such a cavity is indeed squeezed. They obtained results for the transmitted spectrum which showed vacuum-Rabi splitting under conditions of strong atom-field coupling, and sub-natural linewidths, results similar to those of a single atom in a driven optical cavity.⁴ This system is also bistable.
