| Abstract: | A wide angle beam propagation method in an oblique coordinate system (OCS WA BPM) based on coordinate transformation is used to simulate optical waveguides. Compared with conventional wide angle BPM in rectangular coordinate system (RCS WA BPM), much better results are obtained with this method especially for waveguides with large tilted angle. This approach is also applied to Y junctions, and expected results are obtained. |
