摘要
To achieve a polarization-maintaining photonic crystal fiber (PM-PCF) with ultra-high modal birefringence, four types of PM-PCF structure, Traditional, Rim-Touched -4 and -5 (RTS-4 and RTS-5) and Air-Walls structures (AWS), are investigated and compared with each other. A compromising structure with higher birefringence, lower loss and feasibility can be chosen by means of numerical analysis. From the simulation results, the birefringence of the designed RTS-4 PM-PCF with a confinement loss of only about 0.395 dB/km is up to 13.22 x 10(-3) at lambda = 1.55 mu m. Finally, two imperfect conditions of broken wall and thicker wall in the drawing process are investigated to prove that the proposed structure is practicable. (C) 2013 Elsevier B.V.
