Unveiling the Secrets of Ultra-Low Data Loss in Hollow-Core Fibers

Scientists at the University of Bath have developed a mathematical model to explain how antiresonant hollow-core fibers guide light with ultra-low data loss. The researchers' analysis provides a clear explanation for the phenomenon observed in practice, where a hollow-centered optical fiber incorporating glass filaments causes minimal light loss. This breakthrough could lead to the development of new designs for hollow-core fibers that maintain ultra-low data loss, improving the efficiency of optical communication and other applications such as imaging and sensing.
