Cloud-inspired way to guide light: Waveguiding mechanisms could offer new ways to see inside the human body

Photon density modes in curved waveguides. Credit: Nature Physics (2024). DOI: 10.1038/s41567-024-02665-z Inspired by the way sunlight passes through clouds, scientists have discovered an entirely new way to control and direct light. This groundbreaking research, led by physicists at the University of Glasgow, allows light waves to be guided along curved paths tunneled through opaque materials that would normally scatter…
