A rigorous study of polarization rotation in a novel design of high-tunable polarization rotator based on soft glass photonic crystal fiber (PCF) is introduced and analyzed. The suggested PCF has a central hole infiltrated with nematic liquid crystal. At a wavelength of 1.55 <i>μ</i>m, nearly 100% polarization conversion ratio is obtained, with a device length of 558 <i>μ</i>m. The simulation results are evaluated using the full-vectorial finite-difference method along with the full-vectorial finite-difference beam propagation method.
