提出一种基于半导体器件漂移扩散模型并结合交替方向隐式时域有限差分(AD I - FDTD)法的新型全域FDTD法。

A novel global FDTD scheme based on a drift-diffuse model of semiconductor combined alternating direction implicit finite-difference time-domain (ADI-FDTD) method is presented in this paper.

交替方向隐式有限差分波束传输法被用来分析二维限制对称多模波导干涉耦合器。

The alternate-direction implicit finite difference beam propagation method (FD-BPM) is used to analyze the two-dimensional (2D) symmetrical multimode interference (MMI) couplers.
