Metasurfaces with quasi-bound states slash modulation thresholds, bringing momentum bandgaps for light to optical frequencies for the first time.

A reconfigurable silicon ring turns a steady laser into one-way optical pulses and uses a weak return beam to excite, quiet, or synchronize a neighbor.

Wits University and Bordeaux researchers encoded data into optical skyrmions and transmitted it 270 meters through open air, achieving over 98% fidelity without correcting turbulence.

Researchers produce stable laser light that twists like a whirlwind in the lowest energy state using self-organizing torons and a synthetic magnetic field.

A silicon photonic chip device corrects distortions directly in light to enable faster and lower power connections between data centers for large artificial intelligence networks.

Fully optical device uses special crystal to combine sensing and computation, boosting image recognition accuracy while cutting energy use.

Researchers integrate a special thin film that allows direct manipulation of light signals to improve efficiency in data centers facing rising artificial intelligence demands.

Geneva field test—a leap for quantum networks: ytterbium-doped crystal stores entanglement across 8,235 temporal modes over 5.66 km of metropolitan fiber.
