Orbital Angular Momentum Meta‐Holography with Full‐Polarization Control
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.

The monolayer J‐aggregate PTCDI‐C13, grown on thin hBN, is transferred to an all‐dielectric metasurface to achieve strong coupling between optical modes (GMRs and qBICs) and Frenkel excitons. With low losses in both microcavities and excitons, a Rabi splitting of 78 meV is observed in both reflectance and photoluminescence k‐space maps, enabling ...

MEMS‐Tunable Bilayer Plasmonic Metasurfaces for Dynamic Vortex Wave Plates
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
