Correlated Photons from Collective Excitations of Three-Level Atomic Ensemble

, 2006
We systematically study the interaction between two quantized optical fields and a cyclic atomic ensemble driven by a classic optical field. This so-called atomic cyclic ensemble consists of three-level atoms with Delta-type transitions due to the ...
