What is Accurate Analysis of MMI Devices about?

This document summarizes research on using the least squares boundary residual (LSBR) method and vector finite element method to accurately analyze multimode interference (MMI) devices with two-dimensional confinement. The LSBR method satisfies boundary conditions more rigorously than overlap integrals and is used to calculate excitation of modes in the MMI section. Results are presented analyzing a planar MMI structure and an MMI structure with 2D confinement, comparing to more approximate overlap integral
