Researchers at the University of Science and Technology of China have demonstrated skin mode tunability in photonic Floquet lattices. A potential applied at one boundary isolates a skin mode at the opposite boundary, turning it into a self-healing state that recovers its profile after disturbance. The approach enables control of non-Hermitian wave dynamics for mode routing and optical switching. Published in PhotoniX.

An international team from École polytechnique, Collège de France, and HZDR has experimentally realized an all-optical photonic time crystal. Using HZDR’s TELBE terahertz source, they strongly modulated the optical properties of a plasmonic metamaterial on picosecond timescales. This enables ultrafast control of light in the terahertz range and opens paths toward new lasers and optical technologies. Published in Nature.

Researchers observe how a photoinduced hidden state forms within 30 femtoseconds

Wits and UEA researchers reveal a new free-space route to chiral light for sensing and photonics.

When fast-moving electrons pass over nanostructured materials, they can make those materials emit light — a phenomenon called cathodoluminescence, already widely used in electron microscopy. The catch has always been controlling where that light goes once it's generated. Researchers from the University of Southern Denmark, with collaborators at ICFO and AMOLF, have now proposed a theoretical fix: programmable metasurfaces built from individually tunable nanoscale elements, us

A sheet of twisted carbon nanotubes has revealed a hidden talent scientists suspected for decades but had never managed to measure.
