Abstract: We demonstrate in this paper a terahertz free space communication system based on acoustic optical modulation and heterodyne detection. A high resistivity silicon acoustic optical modulator (AOM) was used to modulate a continuous terahertz wave at 2.52 THz. A pyroelectric detector was used to detect the modulated terahertz signal via heterodyne detection mode. A modulation frequency of 937 kHz and sampling rate of 1 kbit/s was achieved.

Keywords:Terahertz, Free space communication, Acoustic optical modulation.
