Birefringence in magneto-optical rib waveguides made by SiO2/TiO2 doped with g-Fe2O3
Résumé
Magneto-optic waveguides are the basic elements for nonreciprocal integrated optics; the phase matching between the fundamental TE and TM modes is an essential condition in magneto-optic waveguides. This condition can be satisfied with selected geometries planar or rib waveguides. We simulated the performance of such devices and determined the waveguide dimensions (height, width, and etching depth) that would allow the same propagation constants for both polarizations TE and TM.
