System guides light through a tiny crystal, undeterred by bumps, bends and back-reflections

Relaying a message from point A to B can be as simple as flashing a thumbs-up at a stranger in an intersection, signaling them to proceed—nonverbal, clear, and universally understood. But light-based communication is rarely ...
