The effect of spontaneously generated coherence on the Goos-Hänchen shifts behavior

, 2014
The behavior of the Goos-Hänchen (GH) shifts of a probe beam reflected from or transmitted through a cavity with a fixed geometrical configuration is theoretically investigated.

Transformation optics for surface phenomena: Engineering the Goos-Hänchen effect

, 2017
Transformation optics, a geometrical recipe for metamaterial design, was originally conceived as a tool to smoothly modify the trajectory of light using continuous coordinate transformations. Here, we show how discontinuous transformations can be used as

Experimental Observation of Laser Planar Trapping

Optics
This study experimentally demonstrates transverse symmetry breaking—a mechanism governing laser planar trapping—and distinguishes its unique role from related phenomena such as the lateral Goos–Hänchen shift and angular deviations.

Goos-hänchen-like shift of three-level matter wave incident on Raman beams

, 2014
When a three-level atomic wavepacket is obliquely incident on a "medium slab" consisting of two far-detuned laser beams, there exists lateral shift between reflection and incident points at the surface of a "medium slab", analogous to optical Goos ...

Giant Goos–Hänchen shift in scattering : the role of interfering localized plasmon modes

, 2014
The longitudinal and transverse beam shifts, namely, the Goos–Hänchen (GH) and the Spin-Hall (SH) shifts are usually observed at planar interfaces. It has recently been shown that the transverse SH shift may also arise due to scattering of plane waves ...

Observation of Goos-Hänchen Shift under Normal Incidence in Slanted TiO2 Nanogratings

npj Nanophotonics
Goos-Hänchen (GH) shifts at natural optical interfaces are typically small. Recent studies have shown that strong optical resonances of metasurfaces and nanogratings can dramatically enhance the GH shifts.

Angular Deviations, Lateral Displacements, and Transversal Symmetry Breaking: An Analytical Tutorial

Photonics
The study of a Gaussian laser beam interacting with an optical prism, both through reflection and transmission, provides a technical tool to examine deviations from the optical path as dictated by geometric optics principles.

Influence of misfit strain on the Goos–Hänchen shift upon reflection from a magnetic film on a nonmagnetic substrate

, 2016
International audienceThe influence of the misfit strain on the lateral shift (Goos–Hänchen effect) experienced by a near-infraredelectromagnetic wave upon reflection from the surface of a bilayer consisting of a magnetic, gyrotropic (i.e ...

Revisiting physical mechanism of longitudinal photonic spin splitting and Goos-Hänchen shift

New Journal of Physics
The intrinsic connection between the transverse photonic spin Hall effect (PSHE) and the Imbert–Fedorov shift has been well characterized. However, physical insights into the longitudinal photonic spin splitting associated with the Goos-Hänchen (GH ...
