An Optimized Configuration of Photonic Crystal Fiber (PCF) for High Birefrigent and Low Loss Application using FDTD Metho

Abstract

Two simplified structures are theoretically designed for high birefringence and low loss guiding photonic crystal fiber at operating wavelength 1.55 μm. The effective index, birefringence and confinement loss are obtained using finite difference time domain method. Simulation result shows that the maximum modal birefringence is equal to 86.33x10-5 for one configuration and lowest confinement loss in another configuration is nearly equal to 0.70x10-2 dB/Km at same operating wavelength
