This paper describes the TE-TM mode conversion in a magneto-optical layer made by a SiO₂/ZrO₂ layer doped with magnetic CoFe₂O₄ nanoparticles. The mode conversion is caused by the Faraday rotation if the magnetization is aligned along the z-axis, parallel to mode propagation. The properties of this phenomenon are simulated using the full-vectorial beam propagation method (BPM). The simulation results show clearly the influence of two parameters in such devices, the first one is the off-diagonal component of tensor that enhances the rotation and the second one, the imaginary diagonal tensor (parameters K ) which makes it suffering from absorption. This result of simulation is an important step to achieve a monolithic integration of optical isolators.
