Scientists just unveiled the world’s first all-optical photonic time crystal — a revolutionary device that manipulates light in time, not space, enabling ultra-fast control of terahertz light. Built with gold and semiconductor plasmonic metamaterials, it harnesses electron waves to trap and guide light on picosecond timescales, slashing energy loss and boosting efficiency. Developed by an international team using Germany’s TELBE terahertz source, this breakthrough could unlock faster optical computing, smarter communications, and next-gen lasers — all by mastering the untapped terahertz…
