Coherent Control of the Goos-Hanchen 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-Hanchen shifts of reflected and transmitted light beams. The dependence of the Goos-Hanchen shifts has been analyzed. It is shown that Goos-Hanchen 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.
