摘要：
In this paper, we demonstrate a spectrally-efficient optoelectronic wireless terahertz (THz) communication system operating at a carrier frequency of 300 GHz. A Complex baseband-over-fiber transmission is achieved by utilizing an optical I/Q modulator on the transmitter side. The THz signal is generated by optical heterodyning in an antenna-integrated photodiode. On the receiver side, an electronic harmonic mixer is used to down-convert the received signal to an intermediate frequency (IF) of 3 GHz, which is then received by a digital storage oscilloscope (DSO) and saved for further offline signal processing. Experimental results of transmission and reception of an orthogonal frequency division multiplexing (OFDM) signal are presented in this work.
