抄録

We present a sub-terahertz (THz) wireless link using photonics-based ultra-low phase noise transmitter and receiver. The maximum data rate achieved below hard-decision forward error correction (HD-FEC) threshold by using on-line signal processing was 240Gbit/s with 64 quadrature amplitude modulation (64QAM) at a single carrier frequency of 275GHz. We also demonstrate successful 20-m transmission at a data rate of over-200Gbit/s data rate. This is the highest single-channel performance ever reported with sub-THz wireless communications to the best of our knowledge.
