AI Insight
Researchers have developed a novel optical fiber created by freezing liquid inside a glass capillary tube. This fiber can simultaneously guide both light and sound waves with coupling efficiency 1,000 times stronger than conventional glass fibers. The enhanced interaction between optical and acoustic waves is achieved through the unique properties of the frozen medium.
Why it matters
The dramatically increased coupling strength could reduce energy consumption in photonic neuromorphic computing and quantum signal processing by several orders of magnitude. This advancement may enable more efficient optical computing systems and quantum communication technologies that require strong light-sound interactions.
