Abstract

A wireless terahertz digital transmission link is demonstrated, in which a quantum-cascade laser and a spectrally-matched quantum-well photodetector serve as the emitter and receiver, respectively. An on-off modulation scheme is used. By directly amplitude modulating the laser emitting at 4.13 THz, a 1.0-Mbps pseudorandom signal is transmitted over a distance of 2.2 m.
