Enhancement of cavity ringdown effect using electromagnetically induced transparency

Wenge Yang, Amitabh Joshi, Min Xiao

Published Jan 1, 2004• 0 citations

Abstract

We show that the unique absorption and dispersion properties of the electromagnetically induced transparency can be used effectively to enhance the cavity ringdown effect. By placing an EIT medium inside an optical resonator, the conditions for observing cavity ringdown oscillations are greatly relaxed.

Enhancement of the cavity ringdown effect based on electromagnetically induced transparency

Wenge Yang, Amitabh Joshi, Min Xiao

We show that the unique absorption and dispersion properties of the electromagnetically induced transparency can be used effectively to relax the conditions for observing the cavity ringdown effect (CRE), which can be useful in applications of CRE in ultrasensitive detection of chemical species. A more straightforward and simple method is used to model the interesting CRE.

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.

Cross Phase Modulation Enhancement by Coupled Cavities and Electromagnetically Induced Transparency

Tomáš Opatrný, D.‐G. Welsch

We propose an optical double-cavity resonator whose response to a signal is similar to that observed in electromagnetically induced transparency (EIT). A combination of such a device with a four-level EIT medium can serve for achieving large cross-Kerr modulation of a probe field by a signal field.

Electromagnetically induced narrow linewidths of optical resonators

Matthias A. Müller, G. Muller, Andreas Wicht +2 more

Summary form only given. We present our work on the modified properties of an optical resonator that contains an electromagnetically induced transparency (EIT) medium. Transparency and steep index of refraction are utilized to reduce the linewidth of the cavity. The influence of the relative intensities of the laser fields is studied, and the results are in good agreement with computer simulations. The linewidth of an optical cavity depends on the phase shift accumulated by the light wave during one round trip. A transparent medium with very strong dispersion causes a very rapidly varying phase shift and would have a remarkable effect on the linewidth of the cavity.

Enhancement of electromagnetically induced transparency cooling by an optical cavity

Jie Zhang, Shuo Zhang, Bao-Quan Ou +2 more

We theoretically investigate an enhanced electromagnetically induced transparency (EIT) cooling method by introducing a high finesse cavity. We find that the quantum destructive interference that is induced by the EIT effect and the cavity coupling can eliminate all of the heating effects in the cooling process by choosing appropriate parameters. Compared with the EIT cooling scheme, a lower final temperature can be obtained under the same conditions in our scheme.

Intracavity electromagnetically induced transparency

Mikhail D. Lukin, Michael Fleischhauer, Marlan O. Scully +1 more

The effect of intracavity electromagnetically induced transparency (EIT) on the properties of optical resonators and active laser devices is discussed theoretically. Pronounced frequency pulling and cavity-linewidth narrowing are predicted. The EIT effect can be used to reduce classical and quantum-phase noise of the beat note of an optical oscillator substantially. Fundamental limits of this stabilization mechanism as well as its potential application to high-resolution spectroscopy are discussed.
