Multispectral Concentric Grafted Perfect Vector Vortex Beam

Laser &Photonics Reviews, EarlyView.
Multispectral structured light offers powerful opportunities for increasing information capacity. A multispectral concentric grafted perfect vector vortex beam is proposed to engineer topological charges and polarization. A metasurface can graft different perfect vector vortex beams across concentric spatial regions and extend this concept to ...

Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography

Laser &Photonics Reviews, EarlyView.
By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

Revealing the Resonant Physics of Open Photonic Time Crystals

Laser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs

Laser &Photonics Reviews, EarlyView.
The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...

Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures

Laser &Photonics Reviews, EarlyView.
A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency
