Abstract

A Y-junction of low-difference refractive-index (RI) and coupler as its input was designed and simulated. The simulation uses COMSOL Multi-Physics Software Package, allowing varying crucial parameters. A detailed analysis and optimization of the device for single-mode design was made, in order to achieve a maximum input area error while preserving a good 50-50 splitting ratio. This approach of combined design and simulations of special Y-junction can benefit and predict advanced optical communication.
