Abstract
L'invention concerne un interféromètre comportant une bobine constituée par un guide d'ondes monomode. Dans cet interféromètre, qui comporte un guide d'ondes monomode 1 constitué sous la forme d'une bobine, il est prévu un coupleur directionnel optique 60 dont l'une de ses quatre entrées et sorties 61 à 64 et une autre 61 de ses entrées et sorties sont raccordées respectivement à une extrémité 101 et à une autre extrémité 100 de la bobine, une troisième entrée 64 étant accouplée par l'intermédiaire d'un dispositif de couplage 27, 26, 90 à une source de lumière 14, et il est prévu un second coupleur directionnel optique 90, formé ainsi que le premier, par les guides d'ondes 601, 602 ; 901, 902. Application notamment aux interféromètres en anneau à guides d'ondes de couplage.
