Sparse‐Aperture Quasi‐Achromatic Spintronic Terahertz Emitter Enabled by Binary‐Phase Metasurface and Multi‐Spectral Intensity Optimization

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
We propose a sparse‐aperture shared‐aperture design with multispectral intensity optimization, enabling a Pt/W binary‐phase metasurface directly integrated with a spintronic emitter. The device achieves quasi‐achromatic focusing across 1.0–1.5 THz, with intensity fluctuation below 33% and edge preservation above 0.68.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...
