Abstract

In this work, modal birefringence and loss characteristic for the fundamental mode in terahertz (THz) polymer elliptical-tube waveguides are investigated by using a full vector finite element method (FEM). Numerical results show that this kind of waveguide has high birefringence (~10^-2) and better loss property as a large part of mode power is trapped in the air-core inside the polymer elliptical-tube. Dependence study of the birefringence on several parameters is also provided and numerical results show the birefringence increases as refractive index and thickness of polymer tube increased.
