Abstract
The first demonstration has been made of the transmission of an audio signal via a THz communication channel using a recently developed room temperature semiconductor THz modulator which is based on the depletion of a two-dimensional electron gas. A standard THz time-domain spectroscopy setup is modified to transmit signals up to 25 kHz over a 75 MHz train of broadband THz pulses.Keywords
