Controlling the Goos-Hänchen shift in a double prism structure using three-level Raman gain medium

Abstract

We propose a scheme to control the Goos-Hänchen (GH) shift of TE and TM reflected light beams in a double-prism structure, where a three-level Raman gain medium is filling the gap between the two prisms. We find that it is possible to control the GH shift in this structure by externally adjusting the optical properties of the Raman gain atomic medium while the gap width between the two prisms is fixed. Inspired by recent successful implementation of the double-prism configuration with an air gap to measure the GH shift, we expected that our proposal to control the GH shift can be achieved experimentally and used in different potential applications of the GH shift.

Goos–Hänchen shifts in a V-type three-level atomic system interacting with squeezed vacuum

“…Quantum interference effects on absorption-dispersion spectra in K-type three-level EIT media interacting with squeezed baths have also been examined [54]. Moreover, recent studies have delved into the manipulation of the GH shift in diverse contexts, such as controlling it in a double prism structure using a three-level Raman gain medium [55] and within cavity optomechanical systems [56].…”
