Modeling and optimization of double-clad Fiber amplifiers using chaotic Propagation of the pump

摘要

A complete theoretical study of double-clad fiber amplifiers is proposed. The notion of chaotic propagation is taken into account in order to improve The pumping process. In addition, a space-time algorithm is used to optimize The distribution of rare-earth dopant in the double-clad fiber. Finally, com- Puted gain curves versus wavelength show attractive results for wavelength Multiplexing applications.
