Correlation-enhanced Goos-Hänchen shift in Rydberg atomic gases

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

“…In a recent study, giant GH shift has been demonstrated to occur at the interface of PT-symmetric bilayer structure due to surface modes 25 . On the other hand, atomic coherence effects which occur in many atomic systems have been widely employed to coherently control the GH shift [26][27][28][29][30][31][32][33][34][35][36] . Because the dispersion as well as the absorption in such systems can be controlled, different proposals based on this idea have been considered to control the GH shift.…”

“…The first proposal to control the GH shift using an atomic medium was considered using a Fabry-Perot cavity filled by a two-level atomic medium 26 , it was shown that the GH shift can be positive or negative by only changing the driving field intensity. Following this work 26 , other different atomic systems have been implemented and showed that the lateral GH shift can be externally controlled using different parameters and properties in each of these these systems [26][27][28][29][30][31][32][33][34][35][36] .…”
