132-Gb/s Photonics-Aided Single-Carrier Wireless Terahertz-Wave Signal Transmission at 450GHz Enabled by 64QAM Modulation and Probabilistic Shaping

摘要

We experimentally demonstrate 132-Gb/s (12-Gbaud) photonics-aided single-carrier PDM-64QAM-PS5.5 THz-wave signal transmission at 450GHz over 20-km fiber-optics and 1.8-m wireless distance with BER under 4×10^{-2. The employment of probabilistic-constellation-shaping significantly improves transmission capacity and system performance.}
