📶 Japanese team hits 112 Gbps at 560 GHz for 6G

Researchers at Tokushima University achieved 112 Gbps wireless speed at 560 GHz, surpassing limits in 6G tech. They used an optical microcomb to reduce power loss and phase noise above 350 GHz.

The microcomb creates ultra-stable laser lines, eliminating phase noise. Two optical signals modulated with QPSK and 16QAM reached 84 Gbps and 112 Gbps respectively. The compact, temperature-controlled device suits practical use.

This targets mobile backhaul links, potentially replacing fiber cables with terahertz wireless beams. The team aims to cut residual noise and develop stronger antennas for longer range.
