Laser &Photonics Reviews, Volume 20, Issue 2, 22 January 2026.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

Programmable Shape‐Directed Optical Binding of Plasmonic Nanoparticles
Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.Shape‐directed optical binding of plasmonic nanoparticles is demonstrated using gold spheres, rods, plates, and decahedra under near‐infrared trapping. Distinct near‐ and far‐field configurations emerge, governed by shape‐dependent scattering and wavelength.

Chirality in optical trapping and optical binding [PDF]
, 2015 Optical trapping is a well-established technique that is increasingly used on biological substances and nanostructures. Chirality, the property of objects that differ from their mirror image, is also of significance in such fields, and a subject of much ...

Rotating Gold Nanomotors for High‐Resolution Mapping of Subcellular Nanomotions
Small Methods, Volume 9, Issue 12, December 1, 2025.A nanomotor‐based method uses optically driven, rotating gold nanorods to detect nanometer‐scale cellular movements with 10 nm spatial and millisecond temporal resolution. Applied to live endothelial cells, the technique reveals subcellular mechanical activity and distinct frequency regimes, capturing transient, localized oscillations.
