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.

Asymmetrically Nonlinear Generation of Optical Orbital Angular Momentum via Cooperation of Bragg Diffraction and Birefringent Phase Matching

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

Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate

Laser &Photonics Reviews, EarlyView.
Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.
