Pengarang : Endra, S.Kom.,MT
Abstract— In this paper I study super-Gaussian pulse propagation in nonlinear fiber optics with solving numerically the Nonlinear Schrödinger Equation (NLSE). The initial pulse has pre-chirped super-Gaussian pulse shape and fiber loss is negligible. I use Symmetrized Split Step Fourier (SSSF) method to solve the NLSE then compare super-Gaussian pulse propagation in nonlinear fiber optics and in linear fiber optics by measuring root mean square (rms) pulse width of pulse that determines the bit rate of fiber. From the results of numerical simulation, I found out that nonlinear fiber gives higher bit rates than linear fiber and effect of pre-chirp and edge sharpness parameter of super-Gausian pulse decreases the bit rate both for linear and nonlinear fiber.
