ABSTRACT:
A magneto-optical waveguide device for changing the radiation modes propagating in the structure comprises a magneto-optical layer in which the modes propagate and which is externally magnetized. This magneto-optical layer is carried by a substrate and is connected to an optically anisotropic structure. This optically anisotropic structure is an artificially formed phase structure having zones of different refractive indices, the zones and their distances from each other in the direction of propagation of the modes being small relative to the wavelength of the light.
