Hybrid Nonlinear InAs/2D‐Graphene/SiO2 Plasmonic Waveguides at 3.55–4.55 μm Mid‐IR: Optical Characterization and Performance

Advanced Photonics Research, Volume 7, Issue 4, April 2026.
Hybrid non‐linear InAs/2D‐graphene/SiO2 dielectric plasmonic waveguide. Configuration #1 (monolayer 2D‐graphene): a single thin layer of 2D‐graphene (thickness tG = 0.34 nm) centered at mid‐plane of one dielectric silica core (SiO2); typical dimensions are: w = width = 500 nm, h = height = 500 nm, total thickness of bulk semiconductor (InAs), 2 tInAs =

Negative group delay of reflected Weyl quasiparticles

New Journal of Physics, 2021
When an electron is incident from a Weyl material to an insulator and totally reflected, it suffers a reflection group delay and a reflection shift (Goos–Hänchen and/or Imbert–Fedorov shifts). We found the group delay is negative for half of the incident

X‐ray waveguide optics at GINIX/P10 PETRA III: recent progress and future directions

Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 298-313, March 2026.
X‐ray waveguide optics enable spatial and coherence filtering of a nano‐focused synchrotron beam and provide tailored illumination wavefronts for holographic imaging. Progress in fabrication, characterization and advanced waveguide interferometers can enhance holographic imaging.Here we report on recent progress in X‐ray waveguide optics for full‐field

Goos–Hänchen and Imbert–Fedorov shifts from a quantum-mechanical perspective

New Journal of Physics, 2013
We study the classical optics effects known as Goos–Hänchen and Imbert–Fedorov shifts, occurring when reflecting a bounded light beam from a planar surface, by using a quantum-mechanical formalism.

Fiber-to-Fiber Optical Switching Based on Gigantic Bloch-Surface-Wave-Induced Goos–Hanchen Shifts

IEEE Photonics Journal, 2013
Fiber-to-fiber on-off optical switching based on the gigantic Goos-Hanchen (GH) shift on an optical beam induced by the Bloch surface wave is experimentally demonstrated for the first time. Through changing the refractive index of the cladding covering a

Interference effect on Goos–Hänchen shifts of anisotropic medium interface

New Journal of Physics, 2023
We present a comprehensive analysis of the anomalous Goos–Hänchen (GH) displacement that occurs during the reflection of light beams at an interface between air and an anisotropic medium. This analysis also applies to the Imbert–Fedorov effect. Our study
