Abstract

We report experimental evidence that light storage, understood as the controlled release of a light pulse by an atomic sample dependent on the past presence of a writing pulse, is not restricted to small-group-velocity media but can also occur in a negative-group-velocity medium. We present a numerical modeling in close agreement with our observations and a simple physical picture applicable to light storage experiments in both ``slow'' and ``fast'' light media.

Storage and retrieval of light pulses in 'slow' and 'fast' light

We have experimentally demonstrated that the storage of light can occur in a coherent atomic medium with an associated negative group velocity. Retrieved optical pulses can only have exponentially decaying slope.

‘Storage of Light’ in a Fast-Light Atomic Medium

We demonstrate both experimentally and by numerical modelling based on the optical Bloch equations that storage and retrieval of optical pulses are remarkably similar in fast-and slow-light atomic media with ground-state Zeeman coherences.

Fast light in atomic media

A. M. Akulshin, Russell McLean

Atomic media have played a major role in studies of fast light. One of their attractive features is the ability to manipulate experimental parameters to control the dispersive properties that determine the group velocity of a propagating light pulse. We give an overview of the experimental methods, based on both linear and nonlinear atom-light interaction, that have produced superluminal propagation in atomic media, and discuss some of the significant theoretical contributions to the issues of pulse preservation and reconciling faster-than-light propagation and the principle of causality. The comparison of storage of light, enhanced Kerr nonlinearity and efficient wave mixing processes in slow and fast light atomic media illustrates their common and distinct features.

‘Storage of light’ in an atomic medium using electromagnetically induced absorption

A. M. Akulshin, A. Lezama, Andrei I. Sidorov +2 more

Storage of light pulses in Rb vapour with bright Zeeman coherences and the associated enhanced absorption and steep negative dispersion is reported. Our experimental observations are qualitatively similar to the well-known proof-of-principle demonstration of light storage (D F Phillips et al 2001 Phys. Rev. Lett. 86 783), but obtained under conditions where electromagnetically induced transparency (EIT) does not exist and the slow-light dark-state polariton model does not apply. Under the present experimental conditions the retrieved pulses obtained in atomic media with dark or bright Zeeman coherences have very similar exponentially decaying slopes which are independent of the shape of the incoming signal pulse. Numerical modelling based on the optical Bloch equations reproduces the essential features of the experimental observations.

From refractive index to stopped light

Jarosław Zaremba

Investigations of controlled modifications of dispersive properties of atomic media and of propagation of short laser pulses have recently become a dynamically developing field of theoretical and experimental researches. In this lecture a brief overview is presented of basic physical phenomena underlying modifications of a group velocity of a pulse propagating in an optically modified medium. In particular, the possibilities of slowing down this velocity to zero and of retrieving the stopped pulse are discussed.
