Abstract :
In the present study, we investigate the evolution of the super continuum generation (SCG) through the triangular photonic crystal fiber (PCF) at 1310nm by using both full-vector multi pole method (M.P.M) and novel concrete algorithms: Symmetric Split-step Fourier (SSF) and fourth order Runge Kutta(RK4) which is an accurate method to solve the general nonlinear Schrodinger equation (GNLSE). We propose an ideal solid-core PCF structure featuring a minimum anomalous group velocity dispersion (GVD), small higher order dispersions (HODs) and enhanced nonlinearity for appropriate super continuum generation with low input pulse energies over discrete distances of the PCF. We also investigate the impact of the linear and nonlinear effects on the super continuum spectra in detail and compare the results with different status.
