Abstract
La présente invention concerne un dispositif (9) de guide d'ondes optique en D de grand diamètre comprenant éventuellement un segment de guide d'ondes rond (11), et en tous cas un segment de guide d'ondes en D (10) constitué d'au moins un noyau (12) entouré d'une gaine (14). Un segment du dispositif de guide d'ondes (9) présente une coupe en forme générale de D faisant au moins environ 0,3 mm selon une dimension transversale (d2). Au moins un réseau de Bragg (16) peut être imprimé dans le guide d'ondes (10) et/ou plusieurs réseaux ou paires de réseaux peuvent être utilisés, de même que plusieurs noyaux. Le dispositif (9) constitue une plate-forme de guide d'ondes robuste permettant, d'une part le couplage de la lumière en entrée et en sortie de guides d'ondes, et d'autre part la fixation et la présentation dans l'axe d'autres guides d'ondes, qu'il s'agisse de noyaux simples ou multiples. Le noyau et/ou la gaine (12, 14) peuvent être dopés avec un dopant à base de terres rares et/ou peuvent être photosensibles. Une partie au moins du noyau peut être dopée entre une paire de réseaux (50, 52) de façon à former un laser-fibre ou le réseau (16). Autrement, cette même partie peut constituer un laser-fibre à rétroaction distribuée (DFB) ou un laser-fibre interactif à l'intérieur du guide d'ondes (10). Ce guide d'ondes peut se présenter sous forme d'un bloc court ou d'une tige longue, en fonction de l'application et des dimensions.
