摘　　要：采用导模传输法分析了二维限制多模干涉器 (MMI)的自映像效应 ,详细讨论了二维限制MMI器件的非对称自映像性质 。The self-imaging effects of multi-mode interference (MMI) devices with two-dimensional confinement are given by using guided-mode propagation analysis method. This paper firstly discusses the asymmetrical characteristic MMI devices with two-dimensional confinement in detail. At the same time, the three-dimensional all-vector finite difference beam propagation method (BPM) is used to confirm the analytical results.
