Goos–Hänchen Lateral Displacements and Angular Deviations: When These Optical Effects Offset Each Other

Photonics, 2022
For optical beams transmitted by a right-angle prism, the Goos–Hänchen shift can never be seen as a pure effect. Indeed, the lateral displacement, caused by the total internal reflection, will always be accompanied by angular deviations generated by the ...

Ultrasensitive label‐free miRNA‐21 detection based on MXene‐enhanced plasmonic lateral displacement measurement

Nanophotonics, Volume 12, Issue 21, Page 4055-4062, October 2023., 2023
Abstract miRNAs are small non‐coding RNA molecules which serve as promising biomarkers due to their important roles in the development and progression of various cancer types. The detection of miRNAs is of vital importance to the early‐stage diagnostics and prognostics of multiple diseases.

Computational Modeling for Intelligent Surface Plasmon Resonance Sensor Design and Experimental Schemes for Real‐Time Plasmonic Biosensing: A Review

Advanced Theory and Simulations, Volume 6, Issue 9, September 2023., 2023
The fundamental principle of Surface Plasmon Resonance (SPR) is the collective oscillation of electrons on the surface of a metal when illuminated with light of a specific wavelength. It offers high sensitivity, real‐time monitoring, label‐free detection, and the ability to analyze complex biological samples.

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 Interaction of 2D Materials With Circularly Polarized Light

Advanced Science, Volume 10, Issue 10, April 5, 2023., 2023
The interaction between 2D materials and circularly polarized light (CPL) provides an attractive control knob for investigating emergent exotic phenomena, especially for chiral‐electronics, photonics, and optoelectronics effects. This review summarizes exciting chiral light‐induced phenomena in representative 2DMs, covering from distinct interaction ...

Sensitivity enhanced tunable plasmonic biosensor using two‐dimensional twisted bilayer graphene superlattice

Nanophotonics, Volume 12, Issue 7, Page 1271-1284, April 2023., 2023
Abstract This study theoretically demonstrated an insight for designing a novel tunable plasmonic biosensor, which was created by simply stacking a twisted bilayer graphene (TBG) superlattice onto a plasmonic gold thin film. To achieve ultrasensitive biosensing, the plasmonic biosensor was modulated by Goos–Hänchen (GH) shift.

Coherent control of Goos-Hänchen shift in a guided-wave surface plasmon resonance structure with Rydberg atoms

Results in Optics, 2021
We proposed an effective and flexible scheme to achieve tunable giant Goos-Hänchen (GH) shift of reflected light in the configuration of guided-wave surface plasmon resonance with Rydberg atoms. With the super atom model of Rydberg atom due to the dipole

Goos-Hänchen and Imbert-Fedorov shifts for the rotating elliptical Gaussian beams

Results in Physics, 2020
We introduce a theoretical research of the Goos-Hänchen (GH) and Imbert-Fedorov (IF) shifts for the rotating elliptical Gaussian beams (REGBs) incidencing on a weakly absorbing semi-infinite medium. We show that the rotation ellipse parameters a, b and c

Topological localized region of Goos-Hänchen shifts in reflection and transmission

Results in Physics, 2023
In this manuscript, the Goos-Hänchen shift of the transmitted and reflected probe beam is controlled and modified. Topologically localized regions are reported in the G-H shift by introducing the position and orbital angular momentum dependency in the ...

The tunnelling of electromagnetic radiation in chirped dielectric structure

EPJ Web of Conferences, 2017
The tunnelling of optical beams through chirped Bragg grating is considered. Lateral shifts of transmitted and reflected beams were calculated. The saturation of Goos-Hanchen shift of transmitted light beams is shown.
