Análisis comparativo del rendimiento de los moduladores Mach-Zehnder y electroabsorción para comunicaciones ópticas.

Abstract

In recent years, the need for capacity has arisen due to the increase in traffic in communication networks. Optical networks have been largely the solution to this need thanks to the frequency characteristic that operates at the THz level. In optical networks, the performance of data transmission is increased by using circuit elements such as optical couplers, optical sensors, optical amplifiers, optical filters and optical modulators. In this study, the principle of operation of the optical modulators, which is one of the optical circuit devices, is analyzed and the importance of the optical modulators is investigated. The effects of the phase, amplitude and frequency of the signal transmitted in the optical modulators are simulated by the software of the OptiSystem 7.0 simulator. In the first chapter it is introduced to the generalities of work. The second chapter describes the theoretical foundations of optical modulators and other optical devices. And finally, the simulation of the modulators is designed to analyze the results obtained and see the impacts on performance.
