Abstract
An extremely low loss porous-core fiber with nearly zero dispersion flattened over a wide band of frequency in the terahertz (THz) regime is presented in this paper. A novel structure of hexagonal air holes in both the core and the cladding is introduced to provide an overwhelming reduction in bulk material absorption loss and confinement loss. Numerical analysis shows that an effective material loss as low as 0.0206 cm−1 and a very flat dispersion of ±0.16 ps/THz/cm can be obtained from the proposed fiber in the frequency range of 0.98–1.64 THz. Within the whole frequency band, the fiber operates in a single-mode region and shows a variation in total loss of only ±0.01 cm−1.
