Theoretical investigations on optical properties of magneto-optical thin film on ion-exchanged glass waveguide

• We model two kinds of magneto-optic matrix (SiO2/TiO2 and SiO2/ZrO2).
• We examine changes in the birefringence in structure on ion-exchanged glass.
• We find the structure that gives rise to the best mode confinement.
• Increasing the refractive index will decrease the quality of mode confinement.

In this work, we report on the theoretical study of magneto-optical waveguides on an ion-exchanged glass waveguide, this latter is made by sol–gel process and doped with magnetic nanoparticles with two kinds of matrix (SiO2/TiO2 and SiO2/ZrO2). The mode propagation and the lateral light confinement for both polarizations TE and TM are simulated using software based on a film mode matching method. We propose from those results magneto-optical waveguides on ion-exchanged glass waveguide geometries for optical integrated applications.
