Abstract

In highly dense gaseous media collective atomic effects become important. We show that three two-level atoms acting collectively and damped by a resonant broadband squeezed vacuum can produce a large refractive index accompanied by vanishing absorption. The squeezed vacuum replaces the usually applied coherent driving field needed to generate atomic coherences which are essential to producing a transparent, high-index material.

Squeezing-induced resonant finite refractive index - zero absorption

We demonstrate that the spectra of a probe beam probing an ensemble of two-level atoms damped by a broadband squeezed vacuum and driven by a weak laser may exhibit a large refractive index accompanied by zero absorption when the probe beam frequency is tuned to the laser frequency. This resonant effect is due to coherent population oscillations. The same theoretical model also exhibits a large refractive index with zero absorption at the Rabi sidebands and near resonance. These results may be verified by present experiments.

ENHANCED INDEX OF REFRACTION IN AN UNDRIVEN SYSTEM

Xiangming Hu, PENG JIN-SHENG, (1)华中师范大学物理系; (2)华中师范大学应用物理研究所

In this paper we show that nondegenerate Λ three-level medium without external coherent driving can produce a large index of refraction at a point of vanishing absorption via the atomic coherence which is induced by the probe field itself.

ENHANCEMENT OF THE INDEX OF REFRACTION VIA QUANTUM INTERFERENCE IN A SIMPLE THREE-LEVEL ATOMIC SYSTEM

Shangqing Gong

The steady state behavior for a simple three-level atomic system has been analyzed. It is shown that the strong coherent driving field can lead to the transparency of the medium to the weak probe field. Furthermore, the same system can also generate a large refractive index with zero absorption.

Producing negative permittivity via quantum coherence and local field effect in dense media

Zhengzheng Zhang, Qiang Lan, Jie Zhang +1 more

A proposal to produce negative permittivity based on the refractive index enhancement and Lorentz–Lorenz local field effect in dense atomic gases is presented. In strongly driving dense two-level atom system, the negative permittivity can be achieved by controlling atom coherence and atomic density. This method will significantly reduce the loss for the propagated optical wave and can be applied to the realization of isotropic single-negative materials in the atomic scale in the optical regime.

Coherent control of optical processes in a resonant medium

Christopher O’Brien

The resonant absorption, emission, and scattering of light are the fundamental optical processes that have been used both to probe matter and to manipulate light itself. In the last decade there has been essential progress in coherent control of both linear and nonlinear optical responses based on resonant excitation of atomic coherence in multilevel quantum systems. Some interesting and useful phenomena, resulting from coherent control of absorption and the group index, such as electromagnetically induced transparency, lasing without inversion, and ultra-slow group velocity of light have been widely studied. This work is focused on coherent control of refractive index and resonant fluorescence in multilevel medium. \n \nWe suggest two promising schemes for resonant enhancement of the refractive index with eliminated absorption and propose their implementation in transition element doped crystals with excited state absorption and in a cell of Rb atoms at natural abundance. We show how to use one of these schemes for spatial variation of the refractive index via its periodic resonant increase/decrease, remarkably keeping at the same time zero absorption/gain. It opens the way to production of transparent photonic structures (such as distributed Bragg reflectors, holey fibers, or photonic crystals) in a homogeneous resonant atomic media such as dielectrics with homogeneously distributed impurities, atomic, or molecular gases. These optically produced photonic structures could easily be controlled (including switching on/off, changing amplitude and period of modulation) and would be highly selective in frequency, naturally limited by the width of the optical resonance. \n \nWe also derive the optical fluorescence spectra of a three-level medium driven by two coherent fields at the adjacent transitions in a general case when all three transitions are allowed. We show that coherent driving can efficiently control the distribution of intensities between the fluorescent channels. In particular, the total intensity of fluorescence at the transition which is not driven by the optical fields may essentially exceed the fluorescence intensity at the driven transitions under the condition of two-photon resonance. This counter-intuitive effect is due to depletion of the intermediate state via atomic interference.
