A novel theoretical analysis model of fiber birefringence and extinction ratio deterioration induced by longitudinal stochastic variation in diameter of silica capillaries for fiber preform is established based on three-dimensional full-vector beam propagation method (3D-FV-BPM) and Jones Matrix method. The longitudinal polarization stability of near-elliptic inner-cladding polarization-maintaining photonic crystal fiber (NEIC-PM-PCF) is analyzed and compared with near Panda clading photonic crystal fiber (NPC-PCF) and near rectangle photonic crystal fiber (NR-PCF) in detail. The longitudinal diameter tolerance ranges of capillaries could be calculated for a given extinction ratio and a certain fiber length, which shows a good reference for fabricating NEIC-PM-PCFs.
