Abstract

A new high birefringence terahertz photonic crystal fiber is proposed. The properties of birefringence, confinement loss, and chromatic dispersion are studied by using full-vector finite-element methods with an anisotropic perfectly matched layers absorption boundary condition. The cladding contains several periodically arranged diamond-shaped units, which consists of four elliptical air holes with uniform parameters. The fiber core is formed by employing a solid unit without elliptical air holes in the center of the cross-section. Through adjusting the structural parameters of the photonic crystal fiber, we can achieve birefringence up to 10⁻³ from 180 to 400 μm. The confinement loss can decrease to 10⁻⁹ dB/m at 100 μm. The chromatic dispersion coefficient D_wis near to 0±1.0 ps/(nm km) from 100 to 400 μm.
