Numerical analysis of plastic hollow core microstructured fiber for Terahertz applications

Abstract Propagation loss and dispersion characteristics of a hollow core microstructured fiber in the THz regime are numerically investigated. The fiber cladding consists of a triangular lattice formed by a periodic arrangement of dielectric tubes of Teflon. Numerical results show that guidance mechanism is the same of kagome and square lattice fibers. Low loss and low dispersion frequency ranges can be tuned just by changing the thickness of the tubes irrespectively of their diameter. Propagation loss four decades lower than the bulk absorption and dispersion lower 0.03 ps/nm km can be obtained over a band of about 1.7 THz centered at 2.1 THz .
