ABSTRACT:
The wave guide is constituted by a film layer C.sub.1 of magnetizable material having a constant refractive index n.sub.1 and placed between two media having refractive indices of lower value than the index n.sub.1. The layer C.sub.1 has two flat parallel surfaces which separate the layer C.sub.1 from the two media which have lower refractive indices and is constituted by a plurality of adjacent regions forming parallel layers, the gyrotropy of at least two of these regions being different.
