Beam Propagation Method and Its Application in SOI Structures
BPM方法在SOI结构中的应用

A fast and accurate ADI BPM program is implemented to simulate the optical transimission at different polarizations.Influence of the selection of PML boundary profile on the base mode field distribution and the base mode propagation constant is investigated.The base mode propagation constant at the different polarizations for the SOI structure waveguides is given.
