Abstract

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.

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 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.

Giant lateral shift via atom–cavity coupling

Salman Khan, Farrah Shafiq, Syed Arif Ullah

We propose a scheme to modify the susceptibility of a two-level coherently driven atomic medium enclosed inside a cavity and to enhance the Goos–Hänchen shift of a probe field via atom–cavity coupling and their detuning. The numerical simulation of the analytical results show that a suitably designed cavity leads to transparency windows both under off- and on-resonance conditions of the probe field. The scheme leads to considerably enhanced lateral shifts, of the order of 760 times the wavelength used, both positive and negative in the transmitted and reflected beams.

Coherent control of the Goos-Hänchen shift

Ziauddin Ziauddin, Sajid Qamar, Muhammad Suhail Zubairy

The behavior of the Goos-H\"anchen (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; however, the GH shifts in the transmitted light remains positive. The corresponding group index of the cavity is positive in both cases.
