Design and Characterization of Porous Core Polarization Maintaining Photonic Crystal Fiber for THz Guidance

Aming, A., Uthman, M., Chitaree, R., Mohammed, W. S. and Rahman, B. M. (2016). Design and Characterization of Porous Core Polarization Maintaining Photonic Crystal Fiber for THz Guidance. Journal of Lightwave Technology, 34(23), pp. 5583-5590. doi: 10.1109/JLT.2016.2623657


An improved design of Teflon photonic crystal fiber with a porous air-core is presented for low-loss terahertz guidance. Optimization of total power confinement in the air-holes, together both in the cladding and core regions, is carried out for both quasi-TE and quasi-TM polarizations by using a full-vectorial finite element method. To achieve the polarization maintenance, modal birefringence is enhanced by destroying the circular symmetry with the introduction of unequal size air-holes in the first ring.
