Highly Birefringent Wideband Residual Dispersion Compensating Photonic Crystal Fiber
نویسندگان
چکیده
We propose a new type highly birefringent spiral photonic crystal fiber (PCF) for residual dispersion compensation in a wide range of wavelengths. The 2-D finite element method (FEM) with perfectly matched boundary layer (PML) is used for numerical simulation. The arrangement and diameter of circular air holes in the designed PCF has been tuned to offer almost flat dispersion profile with average dispersion coefficients of -609.321601 and -396.32923 ps/nm-km for X and Ypolarization, respectively, within the wavelengths of 1350-1600 and 1350-1800nm. The proposed spiral PCF shows high birefringence of 0.0170 and nonlinear coefficient 44.3679 and 28.1431 W -1 km -1 for X and Y-polarization at 1550nm.
