In this paper we propose a Fourier Eigenvector Expansion Method (Fourier-EEM) with coordinate-stretching type PML absorbing boundary conditions. This technique has been used to analyze, under the scalar assumption, 3D optical devices with abrupt discontinuities in the longitudinal direction (i.e. Multimode Interference devices (MMI)). The obtained results clearly confirm the accuracy and efficiency of the proposed approach to calculate the transmission and reflection characteristics of photonic devices.
