With the explosion of wireless data rates, the terahertz (THz) band (0.1-10 THz) is envisioned as a promising candidate to break the existing bandwidth bottleneck and satisfy the ever-increasing capacity demand. The THz wireless communications feature a number of attractive properties, such as potential terabit-per-second capacity and high energy efficiency. In this paper, an overview on the state-of-the-art THz communications is studied, with a special focus on key technologies of THz transceivers and THz communication systems. The recent progress on both electronic and photonic THz transmitters are presented, and then the THz receivers operating in direct-and heterodyne reception modes are individually surveyed. Based on the THz transceiver schemes, three kinds of THz wireless communication systems are reviewed, including solid-state electronic systems, photonics-assisted systems and all-photonics systems. The prospective key enabling technologies, corresponding challenges and research directions for lighting up high-speed THz communication systems are discussed as well.

A packaged resonant tunneling diode (RTD) with rectangular waveguide output for highly integrated wireless communication is proposed. The output signal of the RTD chip is radiated to the rectangular waveguide through an E plane probe transformer. Next, the RTD chip is electrically connected to the transformer by using gold wire bonding. The packaged RTD exhibits an oscillation frequency of 92 GHz, while the maximum radio frequency (RF) output power is −7 dBm. A miniaturized and high data rate wireless communication system with a 7 Gbps on–off keying (OOK) module by using the RTD is demonstrated, and the bit error rate (BER) of the 7 Gbps is below 3.8 × 10−3.

“…For instance, in [12], [18], the first successful transmission of an IEEE 802. 15.3d terahertz signal in the 300 GHz band was reported. A raised cosine (RC) filter, with a roll-off factor of 0.35, was employed to reshape the spectrum of a quadrature amplitude modulated (QAM) signal in the baseband before being up-converted and transmitted over the IEEE band at data rates of 56, 80 and 100 Gbit/s.…”

“…Hence, the prudent utilization of the emission masks admissible by the IEEE 802. 15.3d Standard raises a key challenge in the development of future terahertz communications systems. Despite its importance, this challenge remains under-investigated.…”
