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

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

The new devices use surface waves and interference to control and examine light intensity, phase and polarization in one unit.

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.

Permanently dark and extremely cold craters at the lunar south pole could host a precision device for navigation and scientific measurements on the moon.

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.

Texas A&M researchers create light-powered metajets that move freely without fuel, opening a path to reach nearby stars in decades rather than millennia.
