Phase matched magneto optical single mode rib waveguides based on geometrical adjustments
In this work, we demonstrate via numerical simulation the design rules that must be imposed on the geometry of magneto optical rib waveguides to make them behave as single-mode and phase matched rib waveguides. Using film mode matching method, the results show that operation in both single mode and phase matching is possible under certain circumstances with selected geometries. We simulate the performance of such devices and we determined the waveguide dimensions (height, width, and etching depth) that satisfy single mode and phase matching conditions simultaneously.
