Vortex Beam Lasing from III‐V Nanowires Epitaxially Grown on Silicon‐on‐Insulator

open access: yesLaser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
An epitaxially grown InGaAs nanowire photonic crystal laser on silicon‐on‐insulator is demonstrated to emit vortex beams carrying orbital angular momentum. Deforming the honeycomb lattice causes the band inversion effect and creates symmetry‐protected bound states in the continuum, enabling single‐mode lasing with a topological charge of −2 ...

Uniform Circular Array Antenna for Dual‐Mode Orbital Angular Momentum Generation at 6 GHz

open access: yesInternational Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
Orbital angular momentum (OAM) antennas have recently attracted attention for their potential to enhance communication capacity and and robustness against interference. However, most existing designs rely on complex multilayer feed structures. This work presents a compact, single‐layer, series‐fed dual‐mode OAM antenna composed of four patches arranged
