‘Rainbow on a chip’ research could help unlock faster 6G networks

A Loughborough University-led team has demonstrated a tiny chip that produces precisely spaced frequencies of light, with potential uses in 6G communications and quantum technologies.

A tiny chip developed by at Loughborough University and international partners could help future communications systems carry more information with greater precision.

The device produces a carefully organised spectrum of light, sometimes described as a microcomb, that can be converted into multiple high-frequency millimetre-wave signals.

Researchers say the approach could support higher-capacity 6G communications as well as extremely precise timing for quantum technologies. Because the chip is around the size of a grain of rice, the work also points towards more compact systems.

The is still part of the longer road towards future networks, but it is a good example of UK science pushing the technology forward before 6G reaches everyday devices.
