An electromagnetically induced transparency-like effect is described that allows a strong laser to control and reduce to unity the refractive index of a weak probe. A lossless multistate system with all states far from resonance is considered.

A common choice to select λ so that a measure of noise performance is equal: a common choice is the noise figure (NF). However, this is only applicable when comparing algorithms with identical data. It is thus not suitable to compare across electrode positions or stimulation strategies (as illustrated in the example below). Noise Figure Distinguishability as a noise performance metric for EIT a...

We report the selfand external-dressed AutlerTownes (A-T) splittings of the images of the generated four-wave mixing signal (FWM) and electromagnetically induced transparency (EIT) of probe images in cascade three-level atomic system. Such spatial properties of probe and FWM signals are induced by the enhanced cross-Kerr nonlinearity. We demonstrate the controlled electromagnetically induced sp...

We report hybridization induced transparency (HIT) in a composite medium consisting of a metamaterial and a dielectric. We develop an analytic model that explains HIT by coherent coupling between the hybridized local fields of the metamaterial and the dielectric or an atomic system in general. In a proof-of-principle experiment, we evidence HIT in a split ring resonator metamaterial that is cou...

This paper reviews recent efforts to realize a highefficiency memory for optical pulses using slow and stored light based on electromagnetically induced transparency (EIT) in ensembles of warm atoms in vapor cells. After a brief summary of basic continuous-wave and dynamic EIT properties, studies using weak classical signal pulses in optically dense coherent media are discussed, including optim...
