From: Controlling the Goos-Hänchen shift in a double prism structure using three-level Raman gain medium
(a)–(d) show the GH shifts for the TM-polarized reflected beams as a function of the gap width \(d_{2}\). (e)–(h) show the absolute value of the reflection coefficients for the TM-polarized reflected beams as a function of the gap width \(d_{2}\). In (a) and (e), \(\Omega _{1} = \Omega _{2} = 2 \gamma\). In (b) and (f), \(\Omega _{1} = \Omega _{2} = 5 \gamma\). In (c) and (g), \(\Omega _{1} = \Omega _{2} = 8 \gamma\). In (d) and (h), \(\Omega _{1} = \Omega _{2} = 12 \gamma\). Other parameters are the same as in Fig. 2.
