Transmission and reflection of electromagnetically induced absorption grating in homogeneous atomic media.

All-optical switching and routing based on an electromagnetically induced absorption grating.

An electromagnetically induced absorption grating is formed in a three-level atomic vapor under the condition of electromagnetically induced transparency in which the strong coupling beam is replaced by a standing wave. The transmission and reflection behaviors of the weak probe beam are greatly modified at certain frequencies near the two-photon resonance. An all-optical two-port signal router...

Controlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency

In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...

Electromagnetically induced grating: Homogeneously broadened medium

A strong coupling standing wave, interacting with three-level L-type ~or ladder-type! atoms, can diffract a weak probe field ~propagating along a direction normal to the standing wave! into high-order diffractions, a phenomenon which we name electromagnetically induced grating ~EIG!. We develop in this work a theory for studying EIG in a homogeneously broadened medium consisting of three-level ...

Frequency detuning and power dependence of reflection from an electromagnetically induced absorption grating

شفافیت القایی الکترومغناطیسی در سیستم پلاسمونیکی متشکل از سه تیغه موازی فلز- دی الکتریک- فلز: برهم‌کنش پلاسمون- پلاسمون

In this paper, electromagnetically induced transparency (EIT) in a system consisting of associated arrays of parallel slabs (metal-dielectric-metal) is studied. The transmission coefficient, the reflection coefficient and the absorption coefficient as function of the incident light frequency by using the transfer matrix method is calculated and numerically discussed. Influence of the thickness ...
