This frozen fiber makes light and sound interact 1,000x more stronglyhttps://www.sciencedaily.com/releases/2026/08/260821012228.htm
Freezing the liquid core of an optical fiber produced an extreme environment where light and sound interact more than 1,000 times more strongly than in ordinary fibers. Researchers used the effect to create optoacoustic memory, potentially paving the way for lower-energy photonic computers and advanced quantum technologies.
