Characterization of Photonic Crystal Fibers for Terahertz frequencies

摘要

The emergence of terahertz (THz) technology has opened up a new frontier of fundamental research with many novel applications, such as in imaging and spectroscopy. For these fibers, the waveguiding parameters are easily controllable, when compared to conventional all silica optical fibers and recently there has been an initiative to use such waveguides for guiding THz frequencies. In this context, A rigorous full-vectorial finite element method has been used to obtain the modal solutions of simple, high-density polystyrene dielectric waveguides along with their propagation constants, attenuation characteristics, vectorial modal field profiles, the spot-size and the modal hybridness.
