摘要：

It is well known that in analysing symmetric directional coupler problems only half of the cross-section need be considered, thereby shortening CPU time and reducing the computer memory needed. This simplicity disappears in the case of important devices such as the asymmetric directional coupler. The paper proposes a new methodology which allows fine-mesh finite difference analysis for the modal indices and field profiles of the two lowest supermodes of such an asymmetric structure.
