A composite bilayer metasurface integrates linear‐polarization amplitude–phase modulation with circular‐polarization Pancharatnam–Berry phase modulation, enabling multidimensional terahertz Airy beam manipulation within a single compact aperture. The highly integrated platform supports diverse Airy beam generation and offers new opportunities for ...

All‐Optical Dual‐Angle Diffractive Neural Networks for 2D Direction‐of‐Arrival Estimation
A diffractive neural network with an integrated spatial encoder resolves the direction of an incoming terahertz signal entirely through optical propagation. After the signal passes through the cross‐shaped input and two 3D‐printed diffractive layers, two detector arrays read its two incident angles simultaneously.

Multitask Diffractive Deep Neural Networks Enabled by Joint Distance–Frequency Encoding [PDF]
A joint distance–frequency encoding strategy enables a single passive diffractive neural network to switch among four computational tasks. By combining mechanically tunable layer spacing with a dual‐frequency phase‐independent metasurface, the same hardware performs orbital angular momentum classification, direction recognition, logic operations, and ...

A flexible, wide‐angle‐compatible multispectral stealth metasurface is proposed. It achieves visible camouflage and stable cooperative stealth of 10.6 μm laser and X‐band microwave across the 0°–60° incident range via layered wavelength decoupling. ABSTRACT As electromagnetic detection systems evolve toward multispectral integration and 0°–60° wide ...

Reconfigurable Light Field Generation With Hologram‐Enhanced Multicore Fibers
A novel metafiber platform enables reconfigurable generation of structured light patterns directly at the end of a multicore optical fiber. A 3D‐printed hologram maps individual fiber cores onto predefined image elements, allowing programmable pattern synthesis through selective core excitation.

Toroidal Dipole‐Dominated High‐Performance Optical Sensors via Nanoimprinted Tetramer Architectures
We developed a scalable low‐cost nanoimprinted tetramer architecture (NTA) sensor using two‐step nanoimprint lithography. It comprises polystyrene nanopillar tetramer arrays on a PS waveguide and gold mirror, supporting a toroidal‐dipole‐mediated resonant mode at 810 nm with a simulated Q of 3124.
