✦ Synopsis

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, computed gain curves versus wavelength show attractive results for wavelength multiplexing applications.

## Abstract In this paper, we present a new method, based on the theory of mode analysis, to calculate the absorption efficiency of symmetric or offset double‐clad optical fibers. Both symmetric and offset conditions have been analyzed. In principle, our results are consistent with, but more accura
