This work is focused on the analysis of hollow core photonic band gap fibres (HC-PBGFs) for THz applications. Waveguide design in this spectral region is a major challenge due to the high conductivity losses of metals and high absorption of the dielectrics. HC-PBGFs are dielectric waveguides in which the power fraction propagating in the dielectric is very low, and losses due to material absorption are dramatically reduced. HC-PBGFs have been proposed and developed from the end of 90's for applications in visible and near infrared (NIR) spectrum, and in few years propagation losses have been dramatically reduced from tens of dB/m to few dB/Km.

Abstract
This work is focused on the analysis of hollow core photonic band gap fibres (HC-PBGFs) for THz applications. Waveguide design in this spectral region is a major challenge due to the high conductivity losses of metals and high absorption of the dielectrics. HC-PBGFs are dielectric waveguides in which the power fraction propagating in the dielectric is very low, and losses due to material absorption are dramatically reduced. HC-PBGFs have been proposed and developed from the end of 90's for applications in visible and near infrared (NIR) spectrum, and in few years propagation losses have been dramatically reduced from tens of dB/m to few dB/Km.
