“…The latter are crucial for measuring parameters such as refractive index, displacement, temperature, beam angle, and film thickness [26]. Various structures have been employed to investigate the GH shift, including negative refractive media [27], lossless dielectric slabs [28], photonic crystals [29], systems with different-level configurations [30][31][32][33][34][35][36][37][38][39][40][41][42], and others [43][44][45][46][47][48]. These investigations contribute to a comprehensive understanding of the GH shift phenomenon and its potential applications in a myriad of scientific and technological contexts.…”

This study explores the Goos–Hänchen (GH) shift phenomenon within a cavity hosting a V-type three-level atomic system, engaged with two independent broadband squeezed baths. Our exploration encompasses a thorough analysis of the lateral shifts in both reflected and transmitted light beams, with a focus on the impact of critical factors, i.e, coupling field strength, incoherent pumping field strength, and squeezed vacuum intensity. Our results reveal an interplay of these parameters, resulting in distinctive negative and positive GH shifts in both reflected and transmitted light. In addition, a remarkable enhancement of GH shifts at specific angles of incidence is observed, presenting a wide-ranging modulation across diverse system parameters. This study not only enriches the understanding of the GH shift in complex atomic systems but also highlights the potential for the manipulation of these lateral shifts by fine-tuning key variables of the system, and contributes valuable insights to the broader field of optical phenomena in quantum systems.

“…The presented research considers the Goose-Hänchen shift specifically for the transmitted beam, since, unlike the reflected beam, the lateral shift may attain significantly superior values. Here it is worth noting other ways of controlling the Goose-Hänchen shift in single-layer systems by means of quantum wells [4], optomechanical resonators [5] and in epsilon-near-zero metamaterials [6,7].…”

The structure for implementing resonant optical tunneling effect (ROTE) is a simple layered system of dielectrics that provides full light transmission for resonance condition, despite the presence of barrier layers partially locking light. The presence of a sharp resonant peak both for the intensity and for the spatial shift of the transmitted light beam makes such a structure promising for the creation of sensors and light control devices. This paper focuses on the spatial shift called the Goos-Hänchen shift of such a structure with interfaces of the waveguide layer coated by graphene. The effect of Goos-Hänchen shift near the resonance in this case may be caused by small changes in the chemical potential or the Fermi energy of graphene, which can be controlled both chemically and by electrical bias. The characteristics of transmitted light beam strongly depend on the beam width for the selected optimal focusing condition.

“…no one has considered a fixed medium to study both positive and negative GHS. The negative and positive GHS in the transmitted and reflected light beams without affecting the medium structure have been reported for partial reflection of light [15][16][17][18][19][20][21][22]. Due to its wide range of applications in optical sensing, the lateral shift has been considered as a potential candidate for studying phenomena such as finding the roughness of a surface, measurement of beam angle, irregularities on the surface of a medium, and refractive index measurement [7,23].…”

“…Using the concept of the vortex beam, in this research article, we have a plan to investigate the GHS in the reflected light by considering a cavity having an intracavity medium (in a double-lambda configuration). The phenomenon of the GHS has been studied earlier by using partially coherent light, Gaussian beam, and a plane wave as an incident light [15][16][17][18][19][20][21][22]. In another study, the OAM of structured light is used to control the group velocity [46].…”

We suggest a scheme that consists of a cavity with a four-level double Λ atomic medium as an intracavity medium. The reflection of an optical vortex light beam field that is incident on a cavity has been investigated by consideration within the coherence theory framework. We study the influence of the orbital angular momentum (OAM) of the vortex light beam on the lateral or Goos–Hänchen shift (GHS) for the reflected beam. It has been investigated that different values of OAM from the incident vortex beam enhanced positive and negative GHS. Also, we consider two fields (including incident) that carry an optical vortex interacting with the cavity. We obtain giant positive and negative GHS via manipulation of the OAM corresponding to the two optical vortex beams. To the best of our knowledge, no one has ever studied such a large GHS in a reflected beam.
