Metasurfaces in Adaptive Optics: A New Opportunity in Optical Wavefront Sensing
Laser &Photonics Reviews, EarlyView.Wavefront sensing constitutes a critical component of adaptive optics systems, aimed at quantitatively measuring distorted wavefronts and enabling closed‐loop correction in optical setups. Metasurfaces, as planar optical elements composed of nanoscale structures, provide exceptional freedom in modulating multiple dimensions of the light field.

Laser &Photonics Reviews, EarlyView.Nonlinear orbital angular momentum (OAM) manipulation is crucial for fundamental physics and information technologies. An integrated lithium niobate platform combining Bragg diffraction and birefringent phase matching asymmetrically generates and controls second‐harmonic OAM beams, achieving a normalized conversion efficiency of 10−2 W−1 and supports a

A manifesto for plant science education
PLANTS, PEOPLE, PLANET, EarlyView.Plants provide oxygen, food, shelter, medicines and environmental services, without which human society could not exist. Tackling pressing and global challenges requires well‐trained plant scientists and plant‐aware individuals. This manifesto provides a practical evidence‐based vision to strengthen plant science education, focussed on five strategic ...

Nucleation and Propagation of Traveling Charge Domains in a Planar AlGaN/GaN Triode Structure
physica status solidi (a), EarlyView.This work presents a novel model for the nucleation of charge domain instabilities in semiconductors exhibiting negative differential drift velocity, identifying diffusion as the key factor inhibiting domain formation. A planar Gunn triode structure is proposed which overcomes obstacles to the realization of GaN‐based Gunn effect devices with ...
