Abstract

In this paper a rigorous numerical scheme has been presented for the analysis of a practical multimode interference-based device. The numerical results have been compared with published experimental results to show the validity of the numerical schemes presented. The vector finite element method has been employed to calculate the propagation constants and the least squares boundary residual method has been employed to calculate the excited modal coefficients at the discontinuity interfaces. The power transfer curve is shown for a 3 dB coupler and a 1 X 4 way power splitter is also investigated. The excess loss relating to the power splitter has been shown to be reasonably small around the design length. Finally a 2D multimode interference-based power splitter has been studied, and results reported.
