Abstract

It is well known that quantum coherence and interference are import mechanisms for designing the optical properties of atoms and molecules. Examples are enhancing the index of refraction, large optical Kerr nonlinearities, and cancellation of absorption. These media provide a variety of new applications, such as ultra-slowing of light propagation, superluminal light propagation, ultra-sensitive magnetometer or high-finesse broadband optical cavities.
