Euler‐Top Gaussian Modes: Structured Beams From Quadratic Angular Momentum Dynamics
A new family of structured Gaussian light beams are introduced: Euler‐top Gaussian modes. Their ray‐orbital paths on the Gaussian Poincaré sphere correspond to the polhodes of the Euler top in classical angular momentum theory. This geometric and algebraic construction reveals a nonseparable mode family extending the familiar Hermite‐, Laguerre‐ and ...

Waveguide‐Based Four‐Channel Crosstalk‐Free Metahologram Multiplexed by Diffraction Orders
A diffraction‐order‐multiplexed, four‐channel metahologram integrates a flat glass waveguide and an array of titanium dioxide nanopillars to realize crosstalk‐free holographic projection. Light undergoes total internal reflection within the waveguide and gets out‐coupled by diffraction from the nanopillar array.

Mechanically reconfigurable metasurfaces enable high‐capacity optical storage and holography due to low cost/complexity. A differentiable inverse design framework maps meta‐atom geometries to multichannel optical responses via deep neural networks. Rotatable cascaded metasurfaces optimized through this pipeline achieve pixel‐level holography with 288 ...

Terahertz Encryption With a Polarization‐Sensitive Metasurface
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells
Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,

Phototunable Polarization Volume Gratings Driven by Chiral Hydrazone Switches
Chiral hydrazone photoswitches incorporated into polarization volume gratings enable light‐driven, reversible modulation of optical properties. UV and blue light irradiation reversibly alter the hydrazone isomer ratio, leading to tunable diffraction efficiency and spectral response across the visible spectrum.
