“…Nevertheless, these two schemes rely on pulse-based communications and do not support more spectrum-efficient modulations, which poses a limitation on the maximum achievable data rates. Furthermore, experimental studies in [15]- [17] have shown the feasibility of broadband communications by exploiting the low THz frequencies (i.e., around 0.3 THz) to enable 100 Gb/s wireless links below 20 m. However, the resources including the ultrabroad BW, the modulation scheme, and the transmit power are not jointly and intelligently utilized, by being aware of the distance-BW dependence in the THz band. In this paper, we develop a distance-aware BW-adaptive resource allocation scheme for THz band communication networks with the objective to improve the distance.…”

Terahertz (0.06-10 THz) band communication is envisioned as a key technology to satisfy the increasing demand for ultrahigh-speed wireless links. In this paper, a distance-aware bandwidth-adaptive resource allocation scheme is developed for THz band communication networks, which has the objective to improve the distance. The proposed scheme captures the unique channel peculiarities including the relationship between the distance and the bandwidth, and strategically utilizes the spectrum to enable multiple ultrahigh-speed links. Based on the developed scheme, the subwindows of the THz spectrum, the modulations, and the transmit power are adaptively allocated, for both singleuser and multiuser communications. The numerical results show that the developed resource allocation scheme improves the distances and exploitation of the THz spectrum significantly. Specifically, 10 Gb/s can be supported at 4 m in the multipath channel, while 100 Gb/s is achieved up to 21 m in the line-of-sight transmission with the use of 20 dB gain antennas. Furthermore, in the multiuser network, 14 10 Gb/s links can be supported simultaneously in the multipath channel. With the use of 20 dB gain antennas, 13 100 Gb/s links can be supported at the same time. Moreover, the developed resource allocation scheme outperforms the existing millimeter-wave systems and the nonadaptive scheme. This paper achieves the design objective and contributes to enable multiple ultrahigh-speed links in the THz band communication network.

In this paper, we present a 300 GHz wireless link composed of a photonic uni-traveling-carrier diode transmitter and an active electronic receiver based on millimeterwave integrated circuits fabricated in an InGaAs metamorphic high electron mobility transistor technology. The input pseudo-random binary sequence is transmitted and analyzed offline using fast analog to digital converters. The data transmission reaches 100 Gbps over a distance of 15 m. Complex modulation formats, like 32-Quadrature Amplitude Modulation and 64-Quadrature Amplitude Modulation, are successfully transmitted up to a symbol rate of 8 GBd. The system presents not only high linearity but is also capable of transmitting high symbol rates, up to 40 GBd. To the best of the authors' knowledge, this represents the highest ever reported transmission bandwidth as well as the highest spectral density symbol rate product for transmissions with center frequency in the terahertz band. Thus, the usage of such links in future bandwidth-hungry applications like data centers, data showers, front-and backhaul is proven feasible.
