Soliton microcombs push wireless transmission to record 112 Gbps at 560 GHz for 6G

Japanese researchers demonstrated a photonics-driven 560 GHz wireless link using an optical microcomb and direct-bonded microresonator.

The system delivered 84 Gbps with QPSK and 112 Gbps with 16QAM, marking the first 100 Gbps-class wireless transmission above 420 GHz.

The result points to a practical way past power and phase-noise limits of conventional electronics at sub-THz frequencies.

It could help enable ultra-fast 6G links and high-capacity mobile backhaul in future wireless networks.
