Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or ...

Researchers fabricated an optical element that uses a forest of tiny, antenna-like nanorods, seen here, that together create a metamaterial able to control the spin of light. The metamaterial nanorods ...
