Optical properties of a four-layer waveguiding nanocomposite structure in near-IR regime

The theoretical study of the optical properties of TE- and TM- modes in a four-layer structure composed of the magneto-optical yttrium iron garnet guiding layer on a dielectric substrate covered by planar nanocomposite guiding multilayer is presented. The dispersion equation is obtained taking into account the bigyrotropic properties of yttrium-iron garnet, and an original algorithm for the guided modes identification is proposed. The dispersion spectra are analyzed and the energy flux distributions across the structure are calculated. The fourfold difference between the partial power fluxes within the waveguide layers is achieved in the wavelength range of 200 nm.

Complex waveguide based on a magneto-optic layer and a dielectric photonic crystal

We theoretically investigate the dispersion and polarization properties of the electromagnetic waves in a multi-layered structure composed of a magneto-optic waveguide on dielectric substrate covered by one-dimensional dielectric photonic crystal. The numerical analysis of such a complex structure shows polarization filtration of TE- and TM-modes depending on geometrical parameters of the waveguide and photonic crystal. We consider different regimes of the modes propagation inside such a structure: when guiding modes propagate inside the magnetic film and decay in the photonic crystal; when they propagate in both magnetic film and photonic crystal.
