Optical Fiber Meta‐Tips Based on Partial‐Phase Control

Advanced Optical Materials, Volume 13, Issue 17, June 17, 2025.
Optical fibers working as beam splitters or focusing lens are demonstrated, with the aid of a metasurface integrated on the fiber end facet. Metasurfaces based on meta‐atoms featuring partial control of the phase are considered unleashing their potential.

Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber

Advanced Photonics Research, Volume 6, Issue 6, June 2025.
Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for

Analysis of Band Effects in One‐Dimensional Periodic Lattices Using an Enhanced Homogenization Method

Advanced Photonics Research, Volume 6, Issue 6, June 2025.
An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.

Spatially Controlled Optical Vortex Generation Using Low‐Loss Antimony Telluride Metasurfaces

Advanced Photonics Research, Volume 6, Issue 6, June 2025.
The spatially varying vortex beams with the customizable propagation trajectory and the controllable topological charge evolution are demonstrated using the Sb2Te3‐based plasmonic metasurfaces. Benefiting from the dispersion‐free property of the Pancharatnam–Berry phase and the broadband response of polarization conversion efficiency of the nanobrick ...
