“…7(d) for operation over a concrete sidewalk. The environmental conditions for these measurements were a temperature of [16][17][18][19] • C, humidity of 50%-70%, and a variable wind velocity of 5-14 MPH. These plots display the BER as a function of Tx-to-Rx path distance and are not corrected for either the transmitter power or the receiver sensitivity, which is why the results do not vary in a monotonic fashion with frequency.…”

One of the most exciting future applications of terahertz technology is in the area of wireless communications. As 5G systems incorporating a standard for millimeter-wave wireless links approach commercial roll-out, it is becoming clear that even this new infrastructure will not be sufficient to keep pace with the rapidly increasing global demand for bandwidth. One favorable solution that is attracting increasing attention for subsequent generations of wireless technology is to use higher frequencies, above 100 GHz. The implementation of such links will require significant advances in hardware, algorithms, and architecture. Although numerous research groups are exploring aspects of this challenging problem, many basic questions remain unaddressed. Here, we present an experimental effort to characterize THz wireless links in both indoor and outdoor environments. We report measurements at 100, 200, 300, and 400 GHz, using a link with a data rate of 1 Gbit/s. We demonstrate both line-of-sight and non-line-of-sight (specular reflection) links off of interior building walls. This work represents a first step to establish the feasibility of using THz carrier waves for data transmission in diverse situations and environments.

“…For example, using technologies developed by NTT, a team in Japan led by THz communication pioneer Professor Nagatsuma reported realtime transmission rates in amplitude shift keying (i.e. digital amplitude modulation, ASK) amplitude modulation of up to 50 Gbps at 0.3 THz [6] -that is, approximately a thousand times current Wi-Fi! In France, researchers at IEMN have been working on very wide bandwidth communications, and ASK signals of up to 46 Gbps have been measured at 0.4 THz [7] and up to 32 Gbps using complex THz signals (quadrature amplitude modulation) over 25 meters [8].…”

“…We can see that the optoelectronics approach has made significant contributions on delivering very high data rates, particularly above 10 Gb/s. So far the highest singletransmitter bit rate of 100 Gb/s has been achieved at the W-band [8] and 237 GHz [13], and maximum 64 Gb/s based on allelectronics approach [25] and 50 Gb/s based on optoelectronics approach [26] in the frequency range of 300-400 GHz and above have been reported.…”

Abstract-We experimentally demonstrate an optical network compatible high-speed optoelectronics THz wireless transmission system operating at 400-GHz band. In the experiment, optical Nyquist quadrature phase-shift keying signals in a 12.5-GHz ultradense wavelength-division multiplexing grid is converted to the THz wireless radiation by photomixing in an antenna integrated unitravelling photodiode. The photomixing is transparent to optical modulation formats. We also demonstrate in the experiment the scalability of our system by applying single to four channels, as well as mixed three channels. Wireless transmission of a capacity of 60 Gb/s for four channels (15 Gb/s per channel) at 400-GHz band is successfully achieved, which pushes the data rates enabled by optoelectronics approach beyond the envelope in the frequency range above 300 GHz. Besides those, this study also validates the potential of bridging next generation 100 Gigabit Ethernet wired data stream for very high data rate indoor applications. Index Terms-Photomixing, THz photonics, THz wireless communication, ultradense wavelength-division multiplexing (UD-WDM), unitravelling carrier photodiode (UTC-PD).
