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.

Penn physicists led by Bo Zhen have created hybrid light-matter particles that interact strongly enough to compute, pointing toward ultrafast, low-energy optical AI hardware.

MIT engineers have developed a way to generate 3D photonic devices with nanoscale features, by shrinking them after fabrication. In their new study, they created devices in a variety of shapes, including helices and a shape inspired by the wing of a butterfly.

Light-responsive hydrogels are attractive materials for mimicking dynamic microstructures in nature, providing platform for tunable devices in photonics, sensing, and biomedicine.

Light near the surface of ultra-thin optical fibers allows sorting of chiral nanoparticles based on their handedness

Nanohole-induced confinement and charge neutralization deliver bright, stable quantum emission without electrical gating

Technion researchers led by Prof. Guy Bartal have created the first on-chip nanophotonic platform that deterministically generates single-photon quantum skyrmions. Using a gold circular grating to control total angular momentum (TAM) of surface plasmons, the device transforms heralded single photons into robust, topologically protected SAM-OAM entangled states with skyrmion number ±2 — without post-selection or multi-photon entanglement. This breakthrough paves the way for sc
