Abstract
High-speed coherent transmission at 325 GHz is successfully demonstrated with a 20-Gbaud QPSK signal. A frequency-locked terahertz signal can be provided by an optical-modulation-based optical frequency comb signal. A high-gain antenna with a gain of 46 dBi is suitable to extend the transmission distance up to 15 m without requiring a terahertz amplifier.
