Estudio comparativo de sistemas de conversión de longitud de onda usando amplificadores ópticos de semiconductor (SOA)

Abstract

The telecommunications networks have experienced in the last decades a continuous and exponential growth in the flow of information that must handle, for the previous it has become necessary to study the problems of the communications networks and to look for systems capable of providing solutions for the adequacy, Support and improvement of the ability to manage large volumes of data, which is why telecom operators have opted for photonic technology. The technology around photonic devices offers the possibility to use much of the bandwidth of the optical fibers and in this way take care of the high flow of information of the telecommunications systems. Optical technology is an alternative for the processing and transmission of electrical signals, that is, they have been developed and today we are already studying the implementation of purely optical systems that exploit the properties of the optical field for the treatment of analog or digital signals. An optical device that has acquired great importance in signal processing in recent years has been the Semiconductor Optical Amplifier (SOA). The basic structure of an SOA consists of an electrically powered pn junction, which at first was designed for the amplification of optical signals but which are currently most used for the implementation of optical processing systems, in particular for the realization of optical processes. Conversion of wavelength, central aspect of study of this work of degree. The above in order to remedy one of the major problems presented by communications networks and that is precisely the bottleneck that is generated in communication nodes that perform optoelectronic conversion.
