Lying between optical and microwave ranges, the terahertz band in the electromagnetic
spectrum is attracting increased attention. Optical fibers are essential for develo** the full …

Several classes of non-planar metallic and dielectric waveguides have been proposed in
the literature for guidance of terahertz (THz) or T-ray radiation. In this review, we focus on the …

We report on a new class of polymer photonic crystal fibers for low-loss guidance of THz
radiation. The use of the cyclic olefin copolymer Topas, in combination with advanced …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

In the past two decades, the development and steady improvement of terahertz technology
has motivated a wide range of scientific studies designed to discover and develop terahertz …

In this work we report two designs of subwavelength fibers packaged for practical terahertz
wave guiding. We describe fabrication, modeling and characterization of microstructured …

The propagation of pulses through waveguides with sub-wavelength features,
inhomogeneous transverse structure, and high index contrast cannot be described …

Porous fibers have been identified as a means of achieving low losses, low dispersion and
high birefringence among THz polymer fibers. By exploiting optical fiber fabrication …

Photonic crystal fibers present a wavelength-scale periodic microstructure running along
their length. Their core and two-dimensional photonic crystal might be based on varied …

The expanding role of refractive index measurement in many fields including chemistry,
biology and medicine, food industry, process control, and environmental monitoring, has led …
