Appl Opt. 2016 Dec 10;55(35):10030-10037. doi: 10.1364/AO.55.010030.A highly birefringent silica photonic crystal fiber (PCF) is proposed with nanoscale gallium phosphide strips at the core and modified spiral cladding air hole distribution. Optical properties of the PCF are simulated using the finite element method. Significant influences of low-refractive-index slot region confinement and high-index strips confinement are observed for two different modes. This introduces a high birefringence of ∼0. Read More
