Algorithmic pulse transmission in optical fibers

Abstract

Wave propagation is a fundamental phenomenon occurring in several physical systems. this study include the effect of frequency chirping on optical communication device efficiency is investigated theoretically using a simplistic but realistic model for chirped pulses produced in optical fibers that are directly modulated. The propagation of Gaussian and super-Gaussian chirped pulses in a fiber is being considered, by conversant with the Fourier representation for a pulse propagating in a optical fibers(OFs), the idea of the pulse spectrum and conversant with the algorithm for performing linear pulse propagation in a fiber using Fourier transforms. The study will be able to perform discrete Fourier transforms used in the numerical evaluation of Fourier transforms, and through this, one will recognize the reliability of the pulse amplitude along the fiber as well as the intensity of the time for the pulse takes with super-Gaussian pulse, The effect of chirp on the propagation pulse during the optical fiber was also studied, where it was found that the transmission of messages sent during the pulse was not able to transmit the presence of chirp and the appearance of clear distortions in the form and amplitude of the propagation pulse.
