Cylindrical Vector Beam Multiplexing based on All‐Dielectric Fiber Meta‐Tips Enabling High‐Capacity Bidirectional Optical Communication

Laser &Photonics Reviews, EarlyView.
Cylindrical vector beam (CVB) multiplexing offers a viable solution to channel capacity, integration, and unidirectional transmission challenges in fiber‐rich sixth‐generation backbone networks. An all‐dielectric fiber meta‐tip‐enabled CVB multiplexing system is proposed and demonstrated, providing high‐capacity, bidirectional optical interconnects and

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

Laser &Photonics Reviews, EarlyView.
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 ...

MEMS‐Tunable Bilayer Plasmonic Metasurfaces for Dynamic Vortex Wave Plates

Laser &Photonics Reviews, EarlyView.
This work presents a MEMS‐tunable bilayer metasurface for dynamic vortex wave plates at near‐infrared wavelengths. By electrically tuning the separation between the BMS and the MEMS mirror, the device enables reconfigurable switching between l = 2 and l = −1 vortex modes, achieving >80% polarization conversion efficiency, fast response time (9 µs), and

Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions

Laser &Photonics Reviews, EarlyView.
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...
