Ítem Análisis del Amplificador Óptico de Semiconductor y su Aplicación a Sistemas de Regeneración de Onda 2RPerilla Martinez, Victor Hugo; Puerto Leguizamón, Gustavo AdolfoThis undergraduate dissertation work deals with the study of the Semiconductor Optical Amplifier and its configurations to carry out wave regeneration in amplitude and shape of a digital signal. To this aim, we have analyzed the basic operating principles of the amplifier, the physical structures that have been proposed for its construction and mathematical modeling based on material analysis following its size and construction. Mathematical modeling varies if this device is studied as a bulk element, or if considered a device formed by quantum wells or multiple quantum wells. A study of different configurations based on Semiconductor Optical Amplifier allowing wave regeneration in both amplitude and shape was performed. This is known as 2R regeneration of digital signal. Three configurations are mainly analyzed. The first analyzed configuration is known as Mach Zehnder interferometer (MZI).The second configuration uses an element called saturable absorber, in particular an electro-absorber used in cascade with the Semiconductor Optical Amplifier. The third and final configuration is based on cross-gain compression (XGC) and uses cross-gain-modulation (XGM). Finally one of the configurations was chosen to be implemented in a computer simulation tool; in this case the settings used XGC due to their characteristics. Also, a Semiconductor Optical Amplifier of multiple quantum wells was used which was adjusted in such a way that meets certain parameters specified in data sheets. By using this configuration a regenerated signal was obtained and a subsequent analysis of the results was made describing the obtained relevant findings.
