“…the Fourier Transform (F.T.) ofthe optical power, Pe(f) (watts) can be expressed as: e(f)= HT (f).Id (f)' ( 1) Where H(f) is the transfer function of the source and 'd (f) is the F. T. of the injected current (A). The transfer function can be decomposed in two parts:…”

“…The terms of the above equation are described in Optical confinement factor Accordingly with [1], the standard rate equations that use a linear gain-saturation term of the form (1-c)S can possess three dc solution regimes for nonnegative values of injection current, which two of them are nonphysical solutions, characterized for negative power and high power solutions. For the parameter values used in this paper, the nonphysical solutions would happen above a injection current value between 0.5 and 2A [1J, which is higher than typical values applied in these simulations Values used in the simulations of this work are also shown in figs.…”

“…This results primarily from the fact that these softwares offer convenient means for mathematical manipulations and for the visualization of the physical phenomena associated with these disciplines. In addition, the high cost of modern laboratories in this area enhances the interest of a more diversified use of these softwares [1].…”

This paper presents a complete toolbox to be used together with the MATLAB ISIMULINK software. The versatility of this software is used to form analysis blocks in the time and frequency domains, allowing the user to simulate optical fiber links of any topology, as long as the analysis of its performance face changes in the values of its parameters. Results for LED (F.D.), Quantum Well (T.D.) and Fabry Perot (F. D.) LASERS are shown.

A notebook in the software Mathematica is developed here for the analysis of planar multilayer dielectric waveguides with the objective of using it as a didactic computational tool, with a possible inclusion in the electrical engineering package library of this same software. The scattering and guiding phenomena in a given structure are analyzed in the notebook, through the use of the programming facilities of the Mathematica software. The user may thus specify the physical and geometrical parameters to be analyzed or make a choice from a model's library that includes periodic structures such as Bragg reflectors and multiple quantum well (MQW) structures.

“…There is another issue that makes symbolic computation very attractive for electrical engineering (EE) educational point of view. The extensive teaching experience of one of the authors of this paper and a number of articles published over the years 2,7,14 show that many EE students have difficulty in learning technical subjects because they lack sufficient competence in mathematics. This lack of mathematical knowledge makes it difficult for them analyze signals, circuits or in specially to deal with electromagnetic field problems, electric machines analysis and design, antennas and radio propagation, tasks that are heavily dependent on mathematical modeling and manipulation.…”

In the past 40 years Computer Algebra Systems (CAS) has been used extensively in research and industrial applications. This growing use of "computer algebra" or "symbolic computation" makes it very attractive for employing in electrical engineering education. The objective of this paper is to draw the attention of broad engineering and educational circle to the enormous capabilities of symbolic computation to the teaching of electrical engineering. The role and the advantages of using of computer algebra systems in electrical education will be pointed out via a few significant examples. A brief description of computer algebra systems and the current status within electrical engineering education is given in this paper. There is authors' believe that will be an increase use of symbolic computation in higher education in the very near future, due to both computational and educational advantages. 1. Introduction. Computer tools to help professors and students alike in the teaching and learning processes have become very popular in the last two decades. Scores of articles and technical papers can be found in the technical and popular literature referring to different software and hardware tools and the techniques to use them in educational environments 2-6 , probably due to the incredible advances in software and hardware development, in the last two decades and their significant reduced costs. However the main use has been reported in numerical computation, simulation, and computer-aide design. Many authors have illustrated a wide range of applications in different areas, such as electrostatics, circuit analysis, electrical machine analysis and design, electromagnetics, etc. As long as computers were capable only working with numbers, their applications in engineering education was somewhat controversial. Many experts pointed out that the generality being lost if the information is represented in "discrete" forms, only. Anyway, for a student, numerical results may obscure the fact that they follow from a model, which is analytic in nature. Different and unique to their digital nature is using computers for symbolic analysis. In the past 40 years Computer Algebra Systems (CAS) has been used extensively in research and industrial applications. This growing use of "computer algebra" or "symbolic computation" makes it very attractive for employing in electrical engineering education.
