“…11b, the survey of state-of-the-art dielectric-waveguide links clearly shows the advantages of pushing the carrier frequency towards the THz regime. It is particularly noteworthy that the achieved link data rate density, 332 Gbps/mm, is almost 12 times larger than the prior work [92].…”

“…Rapid increases in data transmission rates and densities within computation and communication infrastructures has led the interconnect community to examine alternatives to conventional copper wireline interconnect for intermediate reach (meter-class). Since 2011 [88], there have been a number of works focused on the use of low-loss dielectric waveguides, carrying modulated data with carriers mostly at D-band (110∼170 GHz) [89]- [92]. Data rate of up to 36 Gbps, meter-level transmission distance and energy efficiency of a few pJ/bit are demonstrated.…”

Silicon-based terahertz (THz) integrated circuits (ICs) have made rapid progress over the past decade. The demonstrated basic component performance, as well as the maturity of design tools and methodologies, have made it possible to build high-complexity THz integrated systems. Such implementations are undoubtedly highly attractive due to their low cost and high integration capability; however, their unique characteristics, both advantageous and disadvantageous, also call for research investigations into unconventional systematic architectures and novel THz applications. In this paper, we review Manuscript

“…Since the rediscovery of dielectric waveguides (DWGs) as a medium for high data rate transmission at millimeter-wave (mm-wave) frequencies in 2010 [1], a tremendous development has been observed in this field [2,3]. From the beginnings until today, the achievable data rate over 1 m DWG has been tripled from 12 to 36 Gb/s [4]. At the same time, the maximum transmission distance increased from 1 to 15 m [5].…”

“…In order to further increase the data rate, the required components are constantly improved. Besides the optimization of transmitter and receiver units [4,6], the increase in data capacity of DWG systems has been mainly achieved by improving the signal-to-noise ratio (SNR) at the receiver. The use of low-loss materials or different designs (e.g.…”

Despite the great progress in data transmission systems using dielectric waveguides (DWGs) in the millimeter-wave (mm-wave) frequency band (30–300 GHz), the signal distortions caused by DWGs have not yet been fully understood. However, such investigations would help to optimize DWGs as a transmission channel in order to further increase data rate and transmission distance of such systems without the need for more complex transceivers. Therefore, this paper presents a detailed study of the expected signal distortions caused by frequency-dependent attenuation and frequency-dependent group delay of circular DWGs at mm-wave frequencies. Based on a low-complexity digital transmission system, the effects of DWGs on the signal-to-noise ratio and the intersymbol interference at the receiver are evaluated. The figures and equations given in this paper allow the reader to easily calculate the channel properties and signal distortions for a wide range of circular DWGs without the need of finite element method solver or other time-consuming numerical simulations. Finally, design recommendations are given to minimize signal distortions for transmitting signals along DWGs.

“…rectangular or circular cross-sections). In recent publications the transmission of linearly polarized waves along dielectric waveguides with these crosssections has been demonstrated in high data rate links under laboratory conditions [5,6]. The mode that is excited in the DWG for these applications is the fundamental mode HE 11 .…”

A growing interest in dielectric waveguides (DWGs) as an alternative to commonly used waveguides (like coaxial or twisted-pair cables) for high data rate interconnects could be observed in the last few years. Especially in the mm-wave frequency range (30–300 GHz) applications with these waveguides benefit from low losses and low dispersion. Moreover, using both polarizations of the fundamental mode in such waveguides could theoretically double the data rate without the need of higher bandwidth or additional fibers. The connection between DWGs and commonly available transceiver chips requires broadband transitions from planar waveguides like microstrip lines to DWGs. In this paper, an overview of the current developments of such transitions is given and a novel low-complexity design is presented that reduces the space consumption by 35% related to recently published works. This allows an easy integration into a printed circuit board layout or a chip package. Furthermore, an extensive sensitivity analysis is presented to prove the robustness toward manufacturing tolerances. The transition is realized at W-band frequencies (75–110 GHz) and achieves a relative 10 dB-bandwidth of more than 25% with a minimum insertion loss of 1.2 dB. It is shown that these properties even hold for manufacturing tolerances of nowadays manufacturing processes.
