Compact Generation of Ultraviolet Structured Light via Low‐Loss Dielectric Metasurfaces (Advanced Optical Materials 7/2026)

UV Structured Light Generation via HfO2 Metasurface This cover showcases a low-loss hafnium oxide (HfO2) metasurface for ultraviolet structured light generation. It supports polarization multiplexing and transforms incident Gaussian beams into outputs with tunable topological charge, radial index, and polarization order, offering a compact and versatile chip-scale solution. More details can be found in the Research Article by Cheng Zhang and co-workers (DOI: 10.1002/adom.202501940).
