This paper presents terahertz (THz) wireless communications technologies using photonics-based and electronics-based transmitters at 300-GHz bands. The photonicsbased transmitter with a Schottky-barrier diode (SBD) detector has boosted a bit rate of the wireless transmission up to 24 Gbit/s. As for the electronics-based transmitter, a resonant-tunnelingdiode (RTD) oscillator has been examined together with detectors using the RTD as well as the SBD to achieve a 2.5-Gbit/s transmission.
