Coherently driven three-level atoms in an optical cavity

Huatang Tan, Wenwu Deng

We investigate the generation of two-mode entangled light from cooperative three-level cascade emitters driven by two lasers inside an optical cavity. It is found that through collective coherent population trapping (CPT) to prepare the atomic states close to the coherent superposition state |1 > — |3>/√22 of the top and ground levels, the entanglement and mean photon number of the entangled light can be significantly enhanced in comparison to the case of independent atoms.

We consider N three-level atoms in a single ported-optical ring cavity interacting through two- photon transitions with a cavity mode. The cavity is driven by an external coherent field, with detuning from the interferometer and the atomic transition. Damping of the atoms and the cavity is included.

We describe a white-light cavity scheme based on a cavity quantum electrodynamics system that consists of multiple three-level atoms confined in an optical cavity and coherently driven by a free-space, circularly polarized field. A linearly polarized field is coupled into the cavity mode and its two circular components induce coherent Raman transitions through the normal modes of the coupled atom-cavity system. One circular component of the cavity field experiences anomalous dispersion which enables broadband light transmission through the cavity. We present the experimental demonstration of the broadband light transmission through an optical cavity coupled to cold Rb atoms.
