Programmable Chiral Radiation via Spin‐Decoupled Metasurface with Integrated Compound Phases

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A programmable spin‐decoupled metasurface integrating propagation and geometric phases enables high‐purity chiral radiation with reconfigurable emission direction. Spin‐selective radiators combined with a compound phase decoupling strategy suppress undesired components, while embedded PIN diodes allow real‐time directional control.

Measurement of orbital angular momentum spectra of multiplexing optical vortices

Optics Express, 2016
Optical vortex beams carrying orbital angular momentum (OAM) are widely investigated for their unique performance in recent years. They can be used to extend the capacity of optical communications system due to the orthogonality of different channels. In the receiver side of a multiplexing optical vortices system, verifying the OAM spectrum is of great

Is Computing with Light All You Need? A Perspective on Codesign for Optical Artificial Intelligence and Scientific Computing

Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.
This perspective article considers what computations optical computing can and should enable. Focusing upon free‐space optical computing, it argues that a codesign approach whereby materials, devices, architectures, and algorithms are simultaneously optimized is needed.

Orbital Angular Momentum Meta‐Holography with Full‐Polarization Control

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
This work demonstrates full‐polarization‐controlled orbital angular momentum (OAM) holography using a single‐layer dielectric metasurface. By independently modulating the complex‐amplitude distributions of two circular polarizations, arbitrary spatially varying polarization is achieved while preserving OAM properties.
