Hollow-core breakthrough

Nature Photonics volume 19, pages 1160–1161 (2025)Cite this article

Subjects

A hollow-core optical fibre which surpasses silica fibre’s long-standing limits and provides an attenuation below 0.1 dB/km across a record-wide bandwidth, could yield more energy-efficient communications with lower latency and higher data capacity.
