Mode Conversion in 2D Magneto Photonic Crystals Made of SiO₂/ZrO₂ Matrix Doped With Magnetic Nanoparticles

In this work, we theoretically study the use of magneto-photonic crystal for amplification of the magneto-optical effects, to improve the merit factor. A two dimensional magneto-photonic waveguide device, formed by a triangular lattice of air holes, embedded in SiO₂/ZrO₂ matrix doped with magnetic nanoparticles, is used to study the influence of the volume fraction (VF %) on the mode conversion. We have used the beam propagation method (BPM) to simulate the efficiency coefficient in a planar 2D magneto-photonic waveguide. The influence of VF % on propagation length is studied, and an enhancement in Faraday rotation in 2D magneto photonic crystal is achieved, which proves the ability of the structure to produce magneto-photonic crystal isolator.
