“…Ribbon-type guides [7] based on polymer-clad high index material have been investigated, but still have predicted losses an order of magnitude higher than a high resistivity silicon ribbon, and require dry air for good transmission. Malekabadi [8] gives an excellent review of solid core structures, and presents results in the microwave region, discussing the superiority of high purity silicon; it is seen as the best broad transmission window option [7]. Silicon core fibers have been analyzed as potential waveguides [9], and recent experimental studies on planar guides support the validity of this approach [10].…”

Silicon waveguide structures are a viable alternative for the transmission of signals over a wide range of frequencies, and new fabrication methods are key to increased applications. In this work, THz transparency of silicon-core, silica clad fibers, refined using a traveling solvent method, is demonstrated. The ≈ 200 µm core of these fibers is shown to have good transmission from 4.8-9 µm and 1-7 THz. Fibers were drawn on a conventional optical fiber tower using the scalable molten core technique and CO 2 laser annealed, resulting in large-grain crystalline cores with broadband transmission. The spectral properties are comparable to those of rectangular guides of similar cross-sectional area cut from high resistivity float zone silicon wafers.

“…Recently, suspended dielectric rectangular waveguide (DRW) fabricated from high resistivity silicon (HRS) has emerged as a promising waveguide technology for integrated terahertz circuits, exhibiting very low loss across the terahertz frequency band [4], [5]. In this work, the application of this technology toward the creation of inline waveguide resonators and filters that are suitable for terahertz systems-on-a-substrate is demonstrated.…”

This paper describes the design, fabrication, and experimental characterization of photonic crystal microbeam cavity resonators for the terahertz band implemented using suspended dielectric rectangular waveguide (DRW) in high-resistivity silicon. Electrical quality factors of up to 11 900, combined with small modal volumes of 0.28 and 0.077 mm 3 , are demonstrated for devices operating at 100 and 200 GHz, respectively. The devices are found to be extremely light-sensitive, opening up new opportunities for light-controlled switching devices at terahertz frequencies. It is shown that the quality factor of the resonator can be tuned and the resonance extinguished through photo-illumination with an infrared light-emitting diode (IR LED). Additionally, the questions of thermal tunability and thermal stability of the resonators are examined. The demonstrated resonators are inherently suited to integration with DRW and, by silicon bulk micromachining, represent an attractive approach for realizing microphotonic-integrated circuits for terahertz systems-on-a-substrate.

Abstract-This paper presents for the first time the design, fabrication, and demonstration of micromachined silicon dielectric waveguide based sub-THz interconnect channel for high efficiency, low cost sub-THz interconnect, aiming to solve the longstanding intra-/inter-chip interconnect problem. Careful studies of the loss mechanisms in the proposed sub-THz interconnect channel are carried out to optimize the design. Both theoretical and experimental results are provided with good agreement. To guide the channel design, a new Figure-of-Merit is also defined. The insertion loss of this first prototype with a 6-mm long interconnect channel is about 8.4 dB at 209.7 GHz, with a 3-dB bandwidth of 12.6 GHz.
