High-Sensitivity Goos-Hänchen Shift Sensing via Surface Plasmon Resonance and Beam Displacement Amplification [PDF]

Sensors
Surface plasmon resonance (SPR) sensing technology has been widely utilized in fields such as biomedicine, food safety, and drug screening for real-time, rapid, and label-free detection of biomolecular interactions.

Enhancing angular photonic spin Hall effect at surface plasmon resonance. [PDF]

Nanophotonics
Abstract The photonic spin Hall effect (PSHE) is the deep subwavelength spin component shift of light induced by the spin–orbit interaction of photons. Here, we demonstrate a polarimetric scheme to directly measure the surface plasmon resonance‐enhanced angular PSHE in the Kretschmann configuration using a gold film. In contrast to the weak measurement

The general treatment of giant Goos-Hänchen shift in a slab cavity

Journal of Taibah University for Science, 2020
In this study, the general treatment to obtain negative/positive giant Goos-Hänchen shifts for a slab cavity is provided. We find that there are two main types of giant shifts: The first type (type I) is associated with near-zero reflection coefficient ...

Goos-Hänchen shift in silicene

Results in Physics, 2021
Silicene has a rich phase diagram, which is due to the strong spin–orbit coupling induced by the buckled structure. In this work, the Goos-Hänchen (GH) shift of silicene in different phases is investigated.

On anomalous optical beam shifts at near-normal incidence

APL Photonics, 2022
We develop the theory of optical beam shifts (both Goos–Hänchen and Imbert–Fedorov) for the case of near-normal incidence, when the incident angle becomes comparable with the angular beam divergence.

Coherent Control of the Goos-Hänchen Shift in a Cavity Containing a Five-Level Double-Ladder Atomic System

IEEE Photonics Journal, 2023
In this paper, we proposed a cavity containing an intracavity medium of five-level double-ladder-type atoms with electromagnetically induced transparency to enhance Goos-Hänchen shifts of reflected and transmitted light beams.

Graphene-Assisted Goos–Hänchen Shift in a Planar Multilayer Configuration in the Visible Light Range

Advances in Condensed Matter Physics, 2020
In this paper, the graphene-assisted Goos–Hänchen (GH) shift of the optical beam reflected from a planar multilayer configuration is investigated. The increased positive Goos–Hänchen shifts can be modulated by adjusting the Fermi energy due to graphene ...
