Slow light based on negative refractive-index material

Abstract

Two ways can be used to generate slow light in ordinary right-hand materials through changing the material dispersion and the structural dispersion.With left-handed materials,instead of the above two approaches,slow light can be realized through the cancellation of power flows at the interface of right-and left-handed materials.In this paper,the recent research progresses in the realization of slow light in left-handed materials with negative refractive-index are reviewed.

Fast light, slow light and left-handed light

The propagation of light in dispersive media is a subject of fundamental as well as practical importance. In recent years attention has focused in particular on how refractive index can vary with frequency in such a way that the group velocities of optical pulses can be much greater or much smaller than the speed of light in vacuum, or in which the refractive index can be negative. Treating these topics at an introductory to intermediate level, Fast Light, Slow Light and Left-Handed Light focuses on the basic theory and describes the significant experimental progress made during the past decade. The book pays considerable attention to the fact that superluminal group velocities are not in conflict with special relativity and to the role of quantum effects in preventing superluminal communication and violations of Einstein causality. It also explores some of the basic physics at the opposite extreme of very slow group velocities as well as stopped and regenerated light, including the concepts of electromagnetically induced transparency and dark-state polaritons. Another very active aspect of the subject discussed concerns the possibility of designing metamaterials in which the refractive index can be negative and propagating light is left-handed in the sense that the phase and group velocities are in opposite directions. The last two chapters are an introduction to some of the basic theory and consequences of negative refractive index, with emphasis on the seminal work carried out since 2000. The possibility that "perfect" lenses can be made from negative-index metamaterials-which has been perhaps the most controversial aspect of the field-is introduced and discussed in some detail.

Recent developments in the study of slow light in complex photonic materials

Kosmas L. Tsakmakidis, Edmund I. Kirby, Ortwin G. Hess

We review recent theoretical and experimental breakthroughs in the realm of slow and stopped light in structured photonic media featuring negative electromagnetic parameters (permittivity/permeability and/or refractive index). We explain how and why these structures can enable complete stopping of light even in the presence of disorder and, simultaneously, dissipative losses. Using full-wave numerical simulations we show that the incorporation of thin layers made of an active medium adjacently to the core layer of a negative-refractive-index waveguide can completely remove dissipative losses - in a slow-light regime where the effective index of the guided wave is negative. We, also, review and compare several 'trapped rainbow' schemes that have recently been proposed for slowing and stopping light.

Experimental demonstration of slowing light by oscillatory mode in left-handed waveguides

Tsung-Yu Huang, Tien-Chung Yang, Ta‐Jen Yen

Slowing light has arisen increasing attentions due to its applications for optical switching, optical hard disk and memories. Among several systems to potentially demonstrate the slowing light effect, such as electromagnetic induced transparency (EIT), metamaterial analogue EIT, left-handed waveguides, foremost is the three-layered left-handed waveguides (LHWG). Therefore, by using a negative refraction index medium (NRIM) operated at multiple-angle incidences to construct an LHWG, herein we experimentally demonstrate the effect of slowing light by activating the oscillatory mode at certain frequency. Our results confirmed by introducing E-field (or H-field) distribution and power flow recording in CST simulation software.

Negative Refractive Index in a Four-Level Atomic System

张红军, 龚尚庆, 钮月萍 +2 more

We propose a scheme for realizing negative refractive index in a four-level atomic system. It is shown that such a system can simultaneously exhibit negative permittivity and negative permeability in an optical frequency range. Furthermore, by analysing the dispersion property of the left-handed material, we find that the probe beam can be controlled from superluminal to subluminal or vice versa via choosing appropriate parameters.
