Tiny 3D-printed “light cages” are giving researchers a new way to catch and hold individual particles of light on a chip, a ...

Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through the air instead of relying on radio waves or copper traces. The result is a ...

Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two light beams can exist in the same place without influencing each other; they ...
