Abstract

La présente invention concerne une fibre optique (10) comprenant un noyau central (12) doté d'éléments de terres rares et entouré d'un noyau externe (14) auquel est relié un noyau de pompage (16). Le noyau de pompage (16) est divisé en régions ramifiées, chacune desdites régions étant partiellement reliée au noyau externe (14). Une source d'excitation lumineuse issue du pompage externe est couplée avec chaque région ramifiée (18) du noyau de pompage (16) et se propage dans le noyau externe (14), sans briser pour autant ledit noyau externe (14), et déborde dans le noyau central (12) où elle est absorbée. Les ions des éléments de terres rares contenus dans le noyau central (12) peuvent être stimulés par ladite source de puissance optique reçue, fournissant ainsi l'amplification voulue d'un signal optique se propageant à travers la fibre optique (10).
