Abstract
A solid core high birefringent photonic crystal fiber (PCF) is designed for supercontinuum (SC) generation. The effective refractive index, effective area, nonlinear coefficient, birefringence and dispersion characteristics of the PCF are investigated using the finite element method. The birefringence value of this PCF reaches the magnitude of 10−3 which is required for high precision applications in optical systems. In order to study SC generation higher order dispersion terms and nonlinear coefficient of the birefringent PCF are calculated separately for both the orthogonally polarized modes. Numerical simulation of SC generation in the proposed PCF is analyzed using the coupled nonlinear Schrodinger equation and split step Fourier transform method. The results show that the SC generation in PCF is strongly affected by the input polarization angle, pulse duration, peak power and initial frequency chirp.
