Dr Luke Peters (centre) and colleagues from Loughborough University’s Emergent Photonics Research Centre examine the precisely organised spectrum of light produced by their system, which can be converted into multiple high-frequency signals known as millimetre waves.

“Rainbow-on-a-chip” breakthrough could help unlock 6G networks and precision timing for quantum technologies

A tiny chip that produces a precisely organised “rainbow” of light could help unlock faster, higher-capacity 6G communications and precision timing for quantum technologies.
