🔬 Freezing fiber boosts light-sound interaction 1000x
Scientists managed to make light and sound interact over 1,000 times stronger by freezing liquid inside an optical fiber. Researchers from Max Planck Institute and others achieved this by cooling the liquid core to -196°C using nitrogen. This extreme cold turned the liquid into a solid while still allowing light and hypersonic sound waves to pass through. The team successfully demonstrated optoacoustic memory, storing light information in slow sound waves. This breakthrough could lead to lower-energy photonic computing systems and quantum tech. 💡
