L'invention concerne des amplificateurs à fibre dopée à l'erbium (EDFA) à noyau coaxial ayant une propriété de spectre de gain auto-régulé. Le fonctionnement d'un EDFA à noyau coaxial est basé sur la séparation partielle des trajets lumineux pour différents canaux de longueur d'onde dans les guides d'ondes à couplage directionnel d'une géométrie à noyau coaxial. Le degré d'égalisation des canaux dépend des paramètres géométriques et optiques de l'EDFA à noyau coaxial et des niveaux de puissance relatifs des canaux. Une analyse numérique basée sur la théorie du mode couplé et sur l'équation de débit montre que, dans des conditions entièrement optimisées, un EDFA à noyau coaxial fournit des taux d'égalisation supérieurs à -0.4 dB par dB de déséquilibre de puissance d'entrée dans le cas de deux WDM. chaînes. Une expérience en cascade démontre l'effet des EDFA coaxiaux sur l'égalisation de la puissance des canaux dans les liaisons fibre optique avec un petit nombre de canaux WDM.

Abstract: Coaxial-core erbium-doped fiber amplifiers (EDFA's) having a property of self-regulated gain spectrum are developed. The operation of a coaxial-core EDFA is based on the partial separation of the light paths for different wavelength channels in the directionally-coupled waveguides of a coaxial-core geometry. The degree of channel equalization depends on the geometrical and optical parameters of the coaxial-core EDFA and on relative channel power levels. A numerical analysis based on the coupled-mode theory and on the rate equation shows that, under fully optimized conditions, a coaxial-core EDFA provides equalization rates in excess of -0.4 dB per dB of input-power imbalance in the case with two WDM channels. A cascade experiment demonstrates the effect of coaxial-core EDFA's toward channel-power equalization in fiber links with a small number of WDM channels.
