Air at the center of optical fibers to guide light
With requirements for very high-speed internet on the increase, several research teams are developing a new generation of optical fibers called “hollow-core fibers” that could help to improve certain properties of light propagation compared to conventional glass fibers. This technology, whose performances are progressing rapidly, could be used in low latency communications in 5G networks for example, or in certain optical instruments in medicine or in industry that require high optical power.
