Exploration of Illicit Drug Detection Based on Goos–Hänchen Shift

open access: yesPhotonics, 2023
Amidst the escalating issue of drug abuse, an urgent need for effective illicit drug detection methods has arisen. This paper introduces a novel optical approach utilizing the Goos–Hänchen Shift (GHS) to explore the possibility of on-site rapid detection

Ultranarrow polaritonic cavities formed by one-dimensional junctions of two-dimensional in-plane heterostructures. [PDF]

open access: yesNanophotonics
Abstract We propose two‐dimensional (2D) in‐plane heterostructures, composed of a 2D crystal adjoining a perfect electric conductor (PEC) plane, that enable ultranarrow polaritonic resonant cavities. Specifically, we theoretically investigate the interaction of 2D surface polaritons (2DSPs) with the junction between the 2D crystal and a PEC plane.

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

open access: yesIEEE 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.

Deep-subwavelength engineering of stealthy hyperuniformity. [PDF]

open access: yesNanophotonics
Abstract Light behaviours in disordered materials have been of research interest primarily at length scales beyond or comparable to the wavelength of light, because order and disorder are often believed to be almost indistinguishable in the subwavelength regime according to effective medium theory (EMT).

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

open access: yesAdvances 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 ...

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

open access: yesPhotonics, 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

open access: yesNanophotonics, 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

open access: yesAdvanced 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.
