Abstract

In this paper, novel designs of single and multiple sectioned passive polarization rotators (PRs) based on silica photonic crystal fiber (PCF) are studied and analyzed. The suggested PCF PRs have an L-shaped core region which offers nearly 100% polarization conversion ratio. The simulation results are obtained using the full vectorial finite difference method along with the full vectorial finite difference beam propagation method. The influence of the different waveguide parameters and operating wavelength on the PRs performances are investigated in order to obtain optimum PR designs. The single and multiple sectioned PCF PRs offer nearly 100% polarization conversion ratio with device lengths of 1743 μ m and 1265 μ m, respectively.
