In this study, we report a highly birefringent terahertz (THz) fiber that contains rectangular air slots in the suspended core. The proposed can provide high birefringence of order 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-2</sup> over wide frequency region single-mode operation.

We present, to the best of our knowledge, a new scheme broadband single-polarization optical fiber with high extinction ratio based on surface plasmon resonance (SPR). The double-hole Ge-doped core is modified by integrating stacks conductive and dielectric layers support SPR. strong couplings between guided modes mode can bring about serious polarization loss TM mode, while supporting efficient transmission TE in broadband. achievable be more than 25 dB covering wide telecom band 1.17–1.42...
A double D-shaped hole optical fiber coated with graphene is proposed as a polarizer at the wavelength of 1.55 μm. As planar surfaces holes are both graphene, interaction between core and can be doubled. Moreover, further improved by introducing functional materials into holes. The provides high extinction ratio (ER) low insertion loss, it operates in single polarization mode. ER 42.5 dB 2.5-mm-long achieved for transverse-electric-pass polarizer, loss approximately 1.08 dB. Specifically,...
