Abstract
EDFAs have been used for some years now in building effective long-haul optical systems for the most diverse applications. For some applications, it is necessary to introduce some feedback control laws in order to avoid the generation of transients that could generate impairments in the system. In this paper, we use a multi-objective optimization approach based on genetic algorithms, to study the introduction of PD controllers into systems of cascaded EDFAs. We compare the use of individual controllers for each amplifier to the use of controllers to sets of amplifiers, and develop guidelines that help designers in making decisions while they are developing their own case-specific designs.
