“…Besides these shapes and materials, a number of dielectric waveguides have been proposed by different researchers, but few of them are discussed in this study. A slab dielectric waveguide was introduced in 2013 by Melakabadi et al [67], and they used high resistive silicon because of its high transparency in the THz frequency range. It was found that it has a very low loss and dispersion in the time and frequency domain.…”

Advancement in technology has opened the doors for the terahertz (THz) frequency range to be applied in different fields for various applications. The future communication technology, especially 6G, will also intend to utilize the THz frequency band due to its large bandwidth that has the capabilities to achieve a high data rate. Great losses are presented in the early research into terahertz transmission medium. It is critical to design an appropriate waveguide that can integrate the THz waves into the system efficiently with minimum loss and provides the ease of transmission of data and overcomes the free space loss issues. Communication, sensing, and other application parameters are highly affected by transmission losses; therefore, low transmission loss and dispersion loss waveguide designs are required for proper utilization. In this paper, the review on reduction in the transmission loss in different types of waveguides operating at the Terahertz frequency range is studied. The design and the experimental setup for several classes of THz waveguides for minimizing transmission loss are also discussed. The review study shows that these waveguides can be a promising transmission medium for future 6G communication.

“…Therefore, a silicon platform is suitable for THz circuits to achieve simplicity and efficiency [ 139 ]. In addition to the THz silicon waveguides [ 62 , 63 , 140 , 141 , 142 , 143 ], many other passive functionalities for THz waves have been realized, such as high-Q silicon cavities [ 61 , 64 , 144 , 145 , 146 ], antennas [ 59 , 60 ], time-domain signal processing [ 147 ], and so on. To further reduce the waveguide loss, various waveguide structures are designed (see Figure 10 a).…”

In the last couple of decades, terahertz (THz) technologies, which lie in the frequency gap between the infrared and microwaves, have been greatly enhanced and investigated due to possible opportunities in a plethora of THz applications, such as imaging, security, and wireless communications. Photonics has led the way to the generation, modulation, and detection of THz waves such as the photomixing technique. In tandem with these investigations, researchers have been exploring ways to use silicon photonics technologies for THz applications to leverage the cost-effective large-scale fabrication and integration opportunities that it would enable. Although silicon photonics has enabled the implementation of a large number of optical components for practical use, for THz integrated systems, we still face several challenges associated with high-quality hybrid silicon lasers, conversion efficiency, device integration, and fabrication. This paper provides an overview of recent progress in THz technologies based on silicon photonics or hybrid silicon photonics, including THz generation, detection, phase modulation, intensity modulation, and passive components. As silicon-based electronic and photonic circuits are further approaching THz frequencies, one single chip with electronics, photonics, and THz functions seems inevitable, resulting in the ultimate dream of a THz electronic–photonic integrated circuit.

“…Both the in-plane as well as out-of-plane confinement of THz mode is possible, and its dispersive properties bitrarily b A dielectric WG mainly suffers from frequency dependent material absorption loss. High-resistivity (HR) silicon possess extremely low loss and negligible dispersion up to ~ 3 THz [155], however, it is only useful for chip scale applications. As an example, researchers have theoretically designed HRsilicon based split WG structure (similar to Fig.…”

Abstract-Terahertz (THz) frequency range, lying between the optical and microwave range covers a significant portion of the electro-magnetic spectrum. Though its initial usage started in the 1960s, active research in the THz field started only in the 1990s by researchers from both optics and microwaves disciplines. The use of optical fibers for THz application has attracted considerable attention in recent years. In this article, we review the progress and current status of optical fiber-based techniques for THz generation and transmission. The first part of this review focuses on THz sources. After a review on various types of THz sources, we discuss how specialty optical fibers can be used for THz generation. The second part of this review focuses on the guided wave propagation of THz waves for their transmission. After discussing various wave guiding schemes, we consider new fiber designs for THz transmission.
