In this paper, we have reported a theoretical study of the mode conversion in two-dimensional magneto-photonic crystal waveguide. The structure is formed by a triangular lattice of air holes embedded in a composite matrix SiO₂/ZrO₂ or SiO₂/TiO₂. These new magneto-optical materials are developed by organic-inorganic sol-gel process and doped with ferrite of cobalt nanoparticles (CoFe₂O₄). The modal birefringence and conversion output have been calculated by varying, respectively, the film thickness and the magnetic nanoparticles concentration. The obtained results show an enhancement in the TE-TM mode conversion. Thus, when the amount of cobalt ferrite nanoparticles reaches 39% into sol-gel matrix, the efficiency can reach 95% which proves that such structures have very promising potential for creating integrated optical isolators.
