“…The allocation of spectrum for 6G THz communications is a topic under discussion, and the next scheduled consideration is at the WRC-23 meeting. However, a definitive decision on the matter is not expected until the subsequent WRC-27 [42].…”

“…The THz characteristics research can be roughly categorized into two kinds [14]. The first kind focuses on the effect of different materials or obstacles on the THz propagation mechanisms such as reflection and scattering [106]. The second kind is dedicated to the traditional channel characteristics of the ITU standard models and new channel characteristics in THz bands, such as sparsity, non-stationary in frequency and spatial domains.…”

“…A promising approach to achieve a 100-fold capacity increase of the data rate lies in the expansion of the frequency spectrum to the terahertz (THz) band that covers a range from 0.1 THz to 10 THz [3]. The THz communication has received growing attention in the recent years [4]. Promising frequency bands in the lower THz band are the D-band (110 GHz to 170 GHz) and H-band (220 GHz to 330 GHz) due to their specific low atmospheric attenuation properties, that is favorable for wireless communications [5].…”

“…The advantage of THz waves is their substantial bandwidth. Therefore, ultrawideband (UWB) communications and multi-band communications using frequency division multiplexing (FDM) schemes in the THz band are critical factors in achieving Tbps communication links [4]. Besides communications, the availability of the vast bandwidth plays a vital role in the development of high-resolution sensors for ranging [5], non-destructive imaging [6], 3D imaging [7], and THz spectroscopy for material identification from fingerprints [8][9][10].…”

An ultra-wideband (UWB) interconnect technology using indium phosphide (InP)-based transitions for coupling the output signals from terahertz (THz) photodiodes featuring coplanar waveguide (CPW) outputs to low-loss dielectric rod waveguides (DRWs), is presented. The motivation is to exploit the full bandwidth offered by THz photodiodes without limitations due to standard rectangular waveguide interfaces, e.g., for future high data rate THz communications. Full electromagnetic wave simulations are carried out to optimize the electrical performance of the proposed InP transitions in terms of operational bandwidth and coupling efficiency. The transitions are fabricated on 100-µm thin InP and integrated with silicon (Si) DRWs. Experimental frequency domain characterizations demonstrate efficient THz signal coupling with a maximum coupling efficiency better than -2 dB. The measured 3-dB and 6-dB operational bandwidths of 185 GHz and 280 GHz, respectively, prove the multi-octave ultra-wideband features of the developed interconnect technology. The 6-dB operational bandwidth covers all waveguide bands between WR-12 to WR-3, i.e., a frequency range between 60 and 340 GHz. In addition, the multi-octave performances of the fabricated interconnects were successfully exploited in proof-of-concept THz communication experiments. Using intermediate frequency orthogonal frequency division multiplexing (OFDM), THz communications are demonstrated for several frequency bands using the same interconnect. Considering soft-decision forward error correction, error-free transmission with data rates of 24 Gbps at 80 GHz and 8 Gbps at 310 GHz is achieved.
