Design of Large‐Aperture Hybrid Refractive Metalens System
An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...

Dynamic Generation of Spatially Variable Vector Beams Using Cascaded Moiré Metasurfaces
A three‐layer cascaded moiré metasurface dynamically generates vector beams with tunable polarization order and controllable lateral focal positions. Relative rotation of the first two layers adjusts the conjugate OAM components that form the vector beam, whereas the third layer steers its focus across the transverse plane, preserving the dominant OAM ...

Misaligning Cascaded Liquid Crystal Elements for Continuously Tunable Axial Spin‐Dependent Splitting
Continuously tunable axial spin splitting is achieved by controlling the lateral misalignment of cascaded Pancharatnam‐Berry phase liquid crystal elements. The displacement generates a spin‐dependent quadratic phase, enabling linear, sign‐reversible focal adjustment and dynamic focus interchange for orthogonal circular polarizations.

Dynamic Control of Phase Matching in Nonlinear Metasurfaces Using Pancharatnam–Berry Phase
Can mechanical rotation of a metasurface control the phase of a nonlinear optical signal? In a dual‐metasurface multipass cell, a circularly polarized pump interacts repeatedly with two plasmonic metasurfaces between two mirrors. By exploiting the geometric phase, rotating one metasurface shifts the phase‐matching condition of the second‐harmonic ...

Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array
A silicon photonic beam steerer based on a metalens focal plane array (FPA) monolithically integrates the collimation lens on‐chip while enabling blind‐spot‐free continuous beam steering. Thermo‐optic prisms provide continuous fine‐tuning and more than double the number of resolvable points.
