Abstract
Based on the guided-mode propagation analysis method and the self-imaging effect, the general imaging properties of the two-dimensional multimode interference coupler (2-D MMI) are generalized and discussed. The general formulas for the positions, intensities, and phases of the self-images, and for image overlap in 2-D MMIs are derived. The numbers, positions, intensities, and phases of the self-images are directly related to the position of the input field and the positional number. The self-imaging properties of 2-D MMIs can be regarded as the interference superposition of two orthogonal one-dimensional self-imaging effects. These results are verified by guided-mode propagation analysis.
