Abstract

Electromagnetically Induced Transparency (EIT) is a widely-used quantum interference effect to control absorption and dispersion properties of a medium [1]. Enclosing an EIT medium in an optical cavity offers an enhanced interaction of the medium with well-defined spatio-temporal modes of the electromagnetic field. This scenario can be exploited to realize high-efficiency quantum memories [2,3], as well as to enhance the “giant” non-linearities associated with EIT [4], and potentially produce spectacular non-linear effects at the few photon level [5].
