Highly Erbium-doped fibers characterization and modeling for Erbium Doped Fiber Amplifiers in WDM regime

Autor: Laurent Gasca, Dominique Bayart, Christine Moreau, Christian Simonneau

Publikováno v: Optical Amplifiers and Their Applications.

Simple experiments are used to determine ion-pairs percentage and macroscopic homogeneous upconversion in highly erbium-doped fibers. Using these parameters in a Giles-based model enable to predict Optical-Power-Conversion-Efficiency of WDM-EDFAs wit

Full vector modal analysis of microstructured optical fiber propagation characteristics

Autor: Philippe Roy, Mourad Zghal, Rabah Attia, Gilles Melin, Faouzi Bahloul, Laurent Gasca, Dominique Pagnoux, R. Chatta

Publikováno v: Novel Optical Systems Design and Optimization VII.

Microstructured optical fibers (MOFs) are optical fibers having a periodic air-silica cross-section. The air holes extend along the axis of the fiber for its entire length. The core of the fiber is formed by a missing hole in the periodic structure.
