Abstract

La présente invention concerne un dispositif optique composé d'une fibre optique multinoyau comportant m noyaux agencés selon une symétrie circulaire où m > 1, la fibre optique présentant une région dont la section va en rétrécissant régulièrement. Cette invention concerne également un coupleur optique composé d'une fibre optique multinoyau comportant m noyaux qui sont agencés selon une disposition symétrique circulaire et qui sont optiquement couplés au niveau d'une zone de raccordement rétrécie à une autre fibre optique de n noyaux, m et n étant des entiers positifs et m étant supérieur à 1. La fibre optique multinoyau présente des régions dont la section varie de façon constante et qui relient des zones rétrécies à des zones non rétrécies.
