Scientists from Max Planck Institute and Leibniz University cooled a liquid core optical fiber to -196°C. This unexpected move allowed them to study how light and sound interact within the frozen fiber, discovering that they interact more than 1,000 times stronger than in standard fibers.
The transformation of liquids into solids is a common process in nature. For example, lava cools down and hardens into rock, while water freezes into ice during winter. This change affects physical properties like density and refractive index, which influence how sound and light travel through materials.
In manufacturing optical fibers, glass preforms are heated to create loose structures that can be drawn into thin fibers. Light travels through the fiber core, enabling fast data transfer over long distances. Optical fibers have become crucial in modern telecommunications, and scientists have developed specialized fibers for technologies like laser, endoscopes, and sensors.
Researchers from Max Planck Institute of the Science of Light (MPL) and Leibniz University Hannover (LUH) took liquid core optical fibers (LiCOF) to a new level. They cooled the liquid inside the fibers with nitrogen at -196°C, causing the material in the core to change into a solid. Surprisingly, this process did not stop the fiber from carrying light.
The team discovered that both the liquid and frozen sections of the fiber can guide hypersonic sound waves. This led them to study the interaction between light and sound within the frozen fiber. They found that it becomes more than 1,000 times stronger than in standard optical fibers. This phenomenon is called Brillouin-Mandelstam scattering.
This breakthrough has potential applications in photonic neuromorphic computing, where information can be transferred from light to sound waves and back again. The team's discovery could lead to new ways of reducing energy consumption in future computing systems.
