Abstract
High birefringent and low confinement loss of photonic crystal fiber is reported at wavelength 1.55 μm via Full-Vectorial Finite Element Method (FV-FEM). By suitable designing of three ring hexagonal solid core fiber and also by introducing a pair of large holes along x-axis near the core region, high modal birefringence 3 × 10 −3 and low confinement loss 0.019 dB/km are found at wavelength 1.55 μm.
