Abstract
The glass-based THz optical waveguides () disclosed herein are used to guide optical signals having a THz frequency in the range from 0.1 THz to (10) THz and include a core () surrounded by a cladding (). The core has a diameter Din the range from (30) μm to 10 mm and is made of fused silica glass having a refractive index n. The cladding is made of either a polymer or a glass or glass soot and has a refractive index n<nand an outer diameter Din the range from 100 μm to 12 mm. The THz optical waveguides can be formed using processes that are extensions of either fiber, ceramic and soot-based technologies. In an example, the THz waveguides have a dielectric loss D<0.005 at 100 GHz.
