“…More specifically, the split-step Fourier transform is suggested for its high processing speed, stability, and accuracy, along with other techniques such as the Fourier pseudospectral method and the Hopscotch approach, as employed elsewhere for solving other equations [10][11][12][13][14][15][16], which will be comprehensively explained within this framework. Besides, other numerical approaches have recently been developed to report the 1D NLSE by several authors, for more details, see [17][18][19][20][21][22][23][24][25][26]. Additionally, analytical approximations to solve the NLSE might exist by implementing plenty of linearization techniques.…”

In this paper, we present a novel extension of the well-known split-step Fourier transform (SSFT) approach for solving the one-dimensional nonlinear Schrödinger equation (NLSE), which incorporates the fiber loss term. While this essential equation governs the pulse propagation in a lossy optical fiber, it is not supported by an exact analytical solution. In this regard, extended versions of the Fourier pseudospectral method (FPSM) and Hopscotch method (HSM) are effectively established as well to cope with the fiber losses effects associated with the pulses’ propagation through the fiber optics, and thus, numerous comparisons are exhaustively conducted among these three compelling numerical approaches to validate their reliability, stability, and accuracy. Based on this, the MATLAB numerical findings bolster that the extended version of the SSFT approach demonstrates superior performance over the other suggested schemes in simulating the solitons propagation in a lossy optical fiber.

“…[3,4] This transmission characteristic is mainly featured because it causes a time broadening, a spectral narrowing, and a redistribution of the carrier's frequencies or chirp within the pulse that can generate intersymbol interference (ISI). [1,5,6] When ISI appears, the transmission capacity can be highly affected and thus, it may reduce the BL product dramatically. In addition, in many practical applications of optical communications today, pulses are generated by direct modulation of semiconductor lasers because it is a simple and low-cost process where no intermediary elements are needed between the laser light and the modulator.…”

Single‐mode optical fiber is one of the most extended wired transmission media providing broadband high‐speed communications all over the world whose performance highly depends on chromatic dispersion and modulation's effects. The motivation of this study is to offer a graphical analyzer of the propagation of Gaussian and super‐Gaussian light pulses directly modulated in a single‐mode optical fiber subject to chromatic dispersion of first and second‐order. The abstract nature of this electromagnetic phenomenon makes any tool that helps learners of optical fiber its understanding a useful resource. Through interactive learning, it is intended to facilitate the comprehension of the behavior of the fiber and feature its capacity in terms of bandwidth and length depending on different parameters and conditions. Also, the study and recreation of directly modulated pulses propagating in the dispersive fiber cannot only be used to teach the students how to avoid its negative impact but to use it as a mechanism to improve the properties of the whole optical communications system. The proposed analyzer consists of a MATLAB graphical user interface integrating the visualization of pulses in time, frequency and carrier's behavior together with additional graphs to interpret and correct chirp and numerical and textual indicators, menus and dialogs to understand the final outcome.
