Abstract

We present a proposal to manipulate the Goos-Hanchen shift of a TM-polarized light beam via a coherent control field, which is injected into a cavity configuration containing the four-level EIT atomic medium. It is found that the lateral shifts of both reflected and transmitted probe beam can be easily controlled by adjusting the intensity of control field.

Control of the Goos-Hänchen shift of a light beam via a coherent driving field

Li‐Gang Wang, Manzoor Ikram, Muhammad Suhail Zubairy

We present a proposal to manipulate the Goos-H\"anchen shift of a light beam via a coherent control field, which is injected into a cavity configuration containing the two-level atomic medium. It is found that the lateral shifts of the reflected and transmitted probe beams can be easily controlled by adjusting the intensity and detuning of the control field. Using this scheme, the lateral shift at the fixed incident angle can be enhanced (positive or negative) under the suitable conditions on the control field, without changing the structure of the cavity.

Control of the Goos–Hänchen shifts of a probe light beam using phase tunability of the intracavity medium

Arash Radmehr, Mostafa Sahrai, Hamed Sattari

This paper presents the Goos-Hänchen (GH) shifts of a probe light beam in a fixed cavity configuration containing the three level V-type atomic medium. We found that in the presence of decay-induced interference, the lateral shifts of both the reflected and transmitted probe light beam can easily be controlled just by the relative phase of applied fields. We also discuss the intensity of the applied field on GH shifts of the reflected and transmitted probe light beam.

Coherent control of the Goos-Hänchen shift in Otto structure

Magdi Bajusair, Mohammad H. Alhakami, Saeed Asiri

We investigate controlling the lateral Goos-Hänchen (GH) shift for a TM-polarized field reflected from Otto structure containing four level N-type atomic medium. The N-type atomic configuration can be formed by coupling the standard three-level $Λ$ system to an additional upper energy level through a coherent driving field. The medium can then be switched from transparent to absorptive under the effect of the driving field. In the Otto structure, an air gap typically separates a dielectric prism from a metal film. We show that the sign and magnitude of the GH shift can be highly controlled when the air gap is replaced by the coherent atomic medium. This can be achieved by adjusting the strength of the applied fields to the atomic medium, while the geometrical characteristics of the proposed structure are unchanged.

Coherent control of the Goos-Hanchen shift

Ziauddin, Qamar S., Sajid Qamar, Muhammad Suhail Zubairy

The behavior of the Goos-Hanchen (GH) shifts in the reflected and transmitted light beam which is incident on a cavity containing an intracavity medium of three-level or four-level atoms with electromagnetically induced transparency (EIT) is discussed. We report a coherent control of the GH shift in a fixed configuration or device via superluminal and subluminal wave propagation. For superluminal wave propagation, we observe negative GH shifts in the reflected part of the incident light whereas the shifts are positive in the transmitted light beam. This corresponds to the negative group index of the cavity in the former case and positive group index of the cavity in the latter. For subluminal wave propagation, the behavior of the GH shifts in the reflected light changes and positive shifts appear

Coherent Control of the Goos-Hänchen Shift in a Cavity Containing a Five-Level Double-Ladder Atomic System

In this paper, we proposed a cavity containing an intracavity medium of five-level double-ladder-type atoms with electromagnetically induced transparency to enhance Goos-Hänchen shifts of reflected and transmitted light beams. The dependence of the Goos-Hänchen shifts has been analyzed. It is shown that Goos-Hänchen shifts can be controlled by modifying the intensity and detuning of the coherent control field without changing material and the structure of the dielectric interface. This work has considerable potential for applications such as optical devices in information processing, flexible optical-beam steering and alignment, optical sensors and optical switches.
