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 ...

Tailoring Second Harmonic Generation via Strong Coupling in a One‐Dimensional Photonic Crystal Heterostructure

Advanced Photonics Research, Volume 6, Issue 6, June 2025.
The strong coupling is investigated as an effective method to modulate the second‐harmonic generation (SHG) in the defect mode and Tamm plasmon resonances. Throughout the entire anticrossing Rabi splitting process induced by strong coupling, the difference in SHG efficiency between two resonances can be modulated by up to two orders of magnitude ...

Goos-Hanchen Shift of the Dispersive Chiral Metamaterials Based on Ω Particles

Nantong Daxue xuebao. Ziran kexue ban, 2021
In order to investigate the reflected beam shifts in the anisotropic chiral metamaterial based on the Ωparticle resonance model, we give the expression of the Goos-H?nchen(GH) shifts of reflected beam by using the stationary phase method.

Topological guided‐mode resonances: basic theory, experiments, and applications

Nanophotonics, Volume 14, Issue 8, Page 1069-1082, April 2025.
Abstract Guided‐mode resonance (GMR) is a key principle for various nanophotonic elements in practice. In parallel, GMR structures offer an efficient experimental platform for fundamental study of novel wave phenomena because of its versatile capability to synthesize complicated potential distributions and analyze deep internal properties conveniently ...

Lateral Beam Shifts and Depolarization Upon Oblique Reflection from Dielectric Mirrors

Annalen der Physik, Volume 536, Issue 6, June 2024.
Potential problems are investigated when dielectric mirrors are used at oblique incidence and found that light beams can experience lateral beam shifts, beam‐shape distortion, and depolarization, which are strongly dependent on wavelength, incident angle, and polarization.

Leaky Waves in Flatland

Advanced Optical Materials, Volume 12, Issue 6, February 23, 2024.
The authors propose a flatland analog of conventional leaky waves, which can be supported by planar junctions of surface impedances. They develop a semi‐analytical model to describe this radiation mechanism and show how it can be exploited to attain highly directive in‐plane propagation.

High-Sensitivity Goos-Hänchen Shifts Sensor Based on BlueP-TMDCs-Graphene Heterostructure

Sensors, 2020
Surface plasmon resonance (SPR) with two-dimensional (2D) materials is proposed to enhance the sensitivity of sensors. A novel Goos–Hänchen (GH) shift sensing scheme based on blue phosphorene (BlueP)/transition metal dichalogenides (TMDCs) and graphene ...

Vortex of beam shift induced by mono-chiral interface states

New Journal of Physics, 2020
If an electron beam hits onto the interface of a Weyl-node-mismatch junction, a shift of the beam center on the interface happens when the beam is reflected or transmitted, where the junction consists of two materials of the same Weyl semimetal and one ...

Quantum reflection time and the Goos-Hänchen effect

Physical Review Research
We explore the analogy between following the motion of a reflected wave packet and a quantum measurement of the spatial delay imposed on the particle by the scattering potential. It is shown that converting such delays into temporal durations can lead to
