Description
Yu Tokizane and a large team send wireless data at 560 gigahertz, far above today's bands, at a record 112 gigabits per second, in a study from 2026. Sixth-generation networks will need such high carriers for back-haul links, since the 300 gigahertz band is crowded. Light-based transmitters had stalled below 350 gigahertz due to noise and weak power.
Their source is a soliton microcomb, a ring of light pulses in silicon nitride that stayed stable for over a day. Two lasers locked to comb lines were mixed in a fast photodiode to make the carrier. Locked lasers gave a cleaner signal than free-running ones. The team sent both simple and dense data formats at high symbol rates, clearing error-correction limits.
