Customizing 3D Polarization Structures at Second Harmonic Frequency
Laser &Photonics Reviews, EarlyView.The nonlinear optical metasurfaces that can generate second harmonic waves (SHWs) and manipulate 3D polarization structures are designed and fabricated. Based on the concept of nonlinear geometric phase, the desired phase distributions of the SHWs are encoded onto the metasurfaces by using gold C3 meta‐atoms.

Orbital Angular Momentum Meta‐Holography with Full‐Polarization Control
Laser &Photonics Reviews, EarlyView.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.

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

Phase‐Retrieved High‐Throughput Multi‐Channel Simultaneous Surface Plasmon Resonance Detection
Laser &Photonics Reviews, EarlyView.This work presents a new phase‐retrieval high‐throughput multi‐channel simultaneous SPR detection framework. By integrating an objective lens‐based coupling system with a rotation‐based ePIE (r‐ePIE) phase retrieval on the back focal planes, this framework significantly reduces the minimum required detection area to reveal localized information.
