This article presents a scheme for few-mode EDFA, which allows to choose independent amplification lengths for different mode groups. The EDF is a dual concentric core fiber, where the central core is connected to the line FMF and the ring core is doped with erbium to provide amplification. The modes of FMF are launched into the central core of...

RÉSUMÉ: Nous proposons une analyse numérique d'une fibre amplifiant les groupes de modes LP11 et LP21 d'une fibre faiblement multimode avec un gain modal différentiel ajustable. La fibre se compose d'un cœur central et d'un cœur annulaire qui est dopé aux ions Er3+. Les modes du cœur central de la fibre amplificatrice sont excités par les modes...

An original concept of integrated few-mode erbium doped fibre ampli- fier for mode division multiplexing (MDM) reaches nearly zero differ- ential modal gain between two mode groups (8 MDM channels) with more than 20 dB of gain.

This article proposes an original concept of a dual-concentric-core few-mode erbium doped fiber (EDF) for amplification of the LP11 and LP21 mode groups of a few mode fiber (FMF) at 1530-nm wavelength with controlled differential modal gain (DMG). The proposed EDF consists of a central core and a ring core. The ring core is doped with Er3+ ions...
