摘要：

A noniterative finite element beam propagation! method (FE-BPM) with a transmission matrix that can treat reflection waves is described for quasi-TE modes propagating in 3-D optical waveguides. The Pade approximation is used for wide-angle beam propagation analysis, and a new approach for determining the transmission matrix is proposed. To show the validity and usefulness of this noniterative FE-BPM, numerical results are presented for the reflection characteristics of 2-D grating optical waveguides and 3-D optical fiber gratings.
