“…Quantum coherence and interference in different coherent media can lead to many interesting phenomena in nonlinear and quantum optics [1][2][3][4][5][6][7][8][9][10][11][12][13]. One of the most interesting phenomena in nonlinear optics is the displacement of a light beam when it is totally reflected and transmitted at a dielectric slab.…”

In this paper, we discuss the phase management of Goos-Hänchen (GH) shifts of a probe light through a cavity with a single-layer graphene nanostructure under a strong magnetic field. By using the quantum mechanical density matrix formalism we study the GH shifts of reflected and transmitted light beams. It is realized that negative or positive GH shifts can be achieved simultaneously by tuning some controllable parameters such as relative phase and the Rabi frequency of the applied fields. Moreover, the thickness effect of the cavity structure is considered as an effective parameter for adjusting the GH shifts of reflected and transmitted light beams. We find that by choosing suitable parameters, a maximum negative shift of 4.5 mm and positive shift of 5.4 mm are possible for GH shifts in reflected and transmitted light. Our proposed model may be useful for developing all-optical devices in the infrared region.

“…Over the past two or three decades, nonlinear quantum optical phenomena based on quantum coherence and interference have been studied theoretically and experimentally in different coherent media [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. These phenomena, due to their potential application in quantum information technologies and all-optical sensors, have been realized in semiconductor nanostructures and solid state media due to their discrete energy levels and strong dipole moment [20][21][22][23][24][25][26][27].…”

In this paper, we discuss Goos-Hänchen (GH) shifts of both reflected and transmitted light beams through a cavity containing single-layer graphene nanostructures. The Landau levels of a single layer graphene medium under a strong magnetic field can interact with infrared and terahertz signal radiation. Therefore, the GH shifts in both reflected and transmitted light beams can be obtained in the infrared and terahertz regions of radiation. We have realized that by controlling some adjustable parameters of the system, such as frequency detuning of applied fields, the Rabi frequency of a coupling field and the polarization of coupling light, the GH shifts can be manipulated in the infrared and terahertz regions. Moreover, the thickness of the intracavity medium is also considered as an important parameter on the behavior of GH shifts spectra.
