In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

Physicists at the University of Warsaw have generated a miniature “laser tornado” inside nanoscale structures by engineering a synthetic magnetic field for photons. The work, announced in March 2026, ...

[bitluni]’s laser-based display pretending to be a an old-school vector CRT. Phosphor-based displays like CRTs rely on the phosphor to emit light for a set amount of time after being activated, ...

Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with ...
