Wide-band terahertz communication at ambient atmosphere

Communication band becomes more and more crowded, terahertz (THz) technology can obtain more than 300GHz frequency, and easy to obtain the transmission rate of Gbit/s. This paper demonstrated the wide-band terahertz communication on a THz time domain spectroscopy system by adding the signal on the photoconductive antenna as bias voltage, and using ZnTe crystal as receiver.
