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.

An optical wave guide comprising a layer C.sub.1 of magnetizable material having a substantially constant optical index of refraction equal to n.sub.1 throughout said layer and a predetermined thickness disposed between two parallel media each having an optical index of refraction of lower value than the index n.sub.1, the said predetermined thickness C.sub.1 corresponding to the distance between said media, wherein the layer C.sub.1 exhibits distributed gyrotropy as herein defined and comprises a plurality of adjacent regions constituting sublayers which are parallel to each other and has two parallel flat surfaces which separate the layer C.sub.1 from the two media having optical indices of lower value than the index n.sub.1.
An optical wave guide comprising a layer C.sub.1 of magnetizable material having a substantially constant optical index equal to n.sub.1 throughout said layer, said layer C.sub.1 being disposed between two media each having an optical index of lower value than the index n.sub.1, said layer C.sub.1 having a predetermined thickness corresponding to the distance between said media, wherein said layer C.sub.1 comprises at least two adjacent regions disposed along planes parallel to the interface between the layer C.sub.1 and the media placed on each side of said layer, at least one of the values of the non-diagonal and non-zero terms of the permittivity tensor being different from one of said regions to the other of said regions.
