124.8-Gbit/s PS-256QAM Signal Wireless Delivery Over 104 m in a Photonics-Aided Terahertz-Wave System

We experimentally demonstrate 16-GBaud probabilistic shaped 256-ary quadrature amplitude modulationsignal transmission over 104-m wireless distance at 339 GHz in a photonics-aided terahertz (THz)-wave communication system. Thanks to the pair of poly tetra fluoroethylene lenses and PS technique, we successfully achieve a record single line rate of 124.8 Gbit/s and net spectral efficiency of 6.2 bit/s/Hz. To the best of our current knowledge, it is the first time to achieve >100 m and >100 Gbit/s single-carrier 256QAM THz-wave signal wireless delivery.
