Abstract
We study the propagation of optical radiation in magnetic waveguides with the periodic domain structures (magneto-photonic crystals). Two types of periodic structures are studied––one- and two-dimensional (1D and 2D). Optical modes conversion is possessed by both the first- and second-order magneto-optic effects and scattering by the domains. In the 2D periodic structures conversion becomes anisotropic and strongly depends on the parameters of the structure. The parameters of the domain structures depend on the external magnetic field, therefore the conversion efficiency can be modulated by the variation of this field. A numerical analysis is provided of the dispersion of the interacting modes as well as of the dependence of the intensity of the converted radiation on the parameters of the domain structure.
