Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

ABSTRACT The growing demands of artificial intelligence require new energy‐efficient and nonvolatile computing paradigms. To meet this challenge, we demonstrate a foundational device platform for optical fiber computing that targets the signal decay and power consumption bottlenecks of conventional systems.

Bayesian optimization combined with in situ quantitative phase imaging enables autonomous correction of layer‐height deviations in projection multi‐photon lithography. By jointly tuning model parameters and grayscale exposure settings, the method achieves more uniform and accurate layers within 300 prints, offering a fast, data‐efficient route to ...

Multispectral Concentric Grafted Perfect Vector Vortex Beam
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 ...
