Abstract :
The first quadrature phase shift keying (QPSK) data link at 385 GHz, using a photonic-based terahertz (THz) emission and a double heterodyne THz detection, is reported. The QPSK signalling is investigated up to 16 Gbaud (32 Gbit/s) on a short range distance, with 20 μW received power levels.
