Birefringence properties of magneto-optic rib waveguide as a function of refractive index

Abstract

We report on the theoretical study of magneto optical rib waveguides with two kinds of silica type matrix doped by magnetic nanoparticles and made by sol– gel process (SiO2/ZrO2 film or SiO2/TiO2). The mode propagation and the light confinement are simulated using software based on a Film Mode Matching method. The modeling is based on geometrical adjustments of the rib waveguide. We propose from those results magneto optical waveguide geometries for optical integrated applications.
