Theoretical Aspects of Thin Film Optical Spectra: Underlying Models, Model Restrictions and Inadequacies, Algorithms, and Challenges

Applied Sciences
Any calculation of thin film optical spectra requires the formulation of certain model assumptions. In general, those model assumptions concern geometrical features as well as material properties.

Experimental Observation of Laser Planar Trapping

Optics
This study experimentally demonstrates transverse symmetry breaking—a mechanism governing laser planar trapping—and distinguishes its unique role from related phenomena such as the lateral Goos–Hänchen shift and angular deviations.

Observation of Goos-Hänchen Shift under Normal Incidence in Slanted TiO2 Nanogratings

npj Nanophotonics
Goos-Hänchen (GH) shifts at natural optical interfaces are typically small. Recent studies have shown that strong optical resonances of metasurfaces and nanogratings can dramatically enhance the GH shifts.

Angular Deviations, Lateral Displacements, and Transversal Symmetry Breaking: An Analytical Tutorial

Photonics
The study of a Gaussian laser beam interacting with an optical prism, both through reflection and transmission, provides a technical tool to examine deviations from the optical path as dictated by geometric optics principles.

Revisiting physical mechanism of longitudinal photonic spin splitting and Goos-Hänchen shift

New Journal of Physics
The intrinsic connection between the transverse photonic spin Hall effect (PSHE) and the Imbert–Fedorov shift has been well characterized. However, physical insights into the longitudinal photonic spin splitting associated with the Goos-Hänchen (GH ...

Goos–Hänchen shifts on spin representation

New Journal of Physics
We analyze the Goos–Hänchen (GH) shift and longitudinal spin splitting (LSS) at a planar interface between two optical media in the spin representation.
