Modeling and simulation of vectorial wave propagation in optical guided-wave devices by beam propagation method

摘要

Summary form only given. Modeling and simulation of electromagnetic wave propagation in optical guided-wave devices by the beam propagation method (BPM) were discussed. The vectorial properties of the propagating waves that are pertinent to many practical optical guided-wave devices were emphasized and illustrated by a newly developed vector beam propagation method (VBPM). The vectorial nature of the propagating waves was taken into account in the new scheme. The polarization dependence and coupling were modeled, and applications of the VBPM to various typical optical guided-wave devices are presented. Comparisons between the scalar and the vector BPMs were made. Some comparisons between the effective-index 3-D and the full 3-D BPMs and the coupled-mode theory and the BPMs were also made.
