Nonlinear optics using electromagnetically induced transparency

Stephen E. Harris, G. Y. Yin

Published Nov 27, 2002• 3 citations

Abstract

It is now well understood that the characteristics of a nonlinear optical process are the result of the interplay of the linear and nonlinear susceptibilities. In general, as an atomic transition to the ground state is approached, the nonlinear susceptibility is resonantly enhanced, but, at the same time, the media exhibits a rapidly increasing refractive index and becomes opaque. During the last several years we have shown how electromagnetically induced transparency (EIT) may be used to dramatically solve this problem.

Nonlinear Optical Processes Using Electromagnetically Induced Transparency

Stephen E. Harris, J.E. Field, Ataç İmamoğlu

It is well known by those practicing the techniques of nonlinear optics, that the power which may be generated in a frequency summing process, or the gain which may be obtained in a parametric process are determined by the interplay of the nonlinear and linear susceptibilities. In general, as an atomic transition to the ground state is approached, the nonlinear susceptibility is resonantly enhanced, but at the same time the media exhibits a rapidly increasing refractive index and becomes opaque.

Nonlinear-optical processes using electromagnetically induced transparency

Stephen E. Harris, J. E. Field, Ataç İmamoğlu

It is well known by those practicing the techniques of nonlinear optics that the power that may be generated in a frequency summing process and the gain that may be obtained in a parametric process are determined by the interaction of tire nonlinear and linear susceptibilities. In general as an atomic transition to the ground state is approached, the nonlinear susceptibility is resonantly enhanced, but at the same time the media exhibits a rapidly increasing refractive index and becomes opaque.

Light Controlling Light with Enhanced Kerr Nonlinearity

Min Xiao, Hai Wang, David J. Goorskey

The Kerr nonlinear index of refraction of a three-level atomic medium can be greatly enhanced by atomic coherence induced by two laser beams. Such electromagnetically induced transparency (EIT) media can be used to generate efficient nonlinear optical processes at low light intensities. Control and enhancement of Kerr nonlinearity in EIT media can be useful in all-optical communication, all-optical computing, and quantum information processing.

Nonlinear Optics Using Electromagnetically-Induced Transparency

K. Hakuta

Recently, there has been increasing interest on the idea of controlling optical responses using atomic-coherence or quantum-interferences. Typical example may be the concept of electomagnetically-induced transparency (EIT) [1]. The key idea of EIT is to apply a strong-coupling field between a metastable and upper states to dress them equivalently as two states decaying to a common level or continuum, and to induce the transparency at the split-center of Autler-Townes components. This idea of EIT may open new possibilities to various coherent processes, such as lasing without population inversion, enhanced refractive index without absorption], slow group velocity without absorption, enhanced nonlinearity without absorption, etc.

Nonlinear optical processes using electromagnetically induced transparency

Stephen E. Harris, J. E. Field, Ataç İmamoğlu

We show that by applying a strong-coupling field between a metastable state and the upper state of an allowed transition to ground one may obtain a resonantly enhanced third-order susceptibility while at the same time inducing transparency of the media. An improvement in conversion efficiency and parametric gain, as compared to weak-coupling field behavior, of many orders of magnitude is predicted.

Novel linear and nonlinear optical properties of electromagnetically induced transparency systems

Min Xiao

We describe some interesting linear and nonlinear optical properties of three-level electromagnetically induced transparency (EIT) systems, such as absorption reduction, sharp dispersion change, and enhanced Kerr nonlinearity. These novel optical properties are very useful in enhancing efficient nonlinear optical processes, which can find applications in optoelectronic devices. We present some experiments done in our group in the past few years with three-level atomic systems, especially more recent experiments with EIT medium inside an optical cavity.
