Abstract

La présente invention concerne un filtre en peigne ou imbricateur à faible niveau de dispersion, comprenant un premier ensemble d'éléments biréfringents comportant au moins un élément biréfringent, et un second ensemble d'éléments biréfringents comportant au moins un autre élément biréfringent. De par leur configuration, les deux ensembles d'éléments biréfringents coopèrent entre eux de façon à atténuer la dispersion de l'imbricateur. Pour réaliser une dispersion presque ou totalement nulle simultanément pour les canaux pairs et impairs, on oriente les axes de polarisation des canaux pairs et impairs de façon qu'ils soient parallèles entre eux avant l'entrée dans le second ensemble d'éléments biréfringents.
