Abstract :
This paper proposed a new mathematical model for optical waveguide analysis. The proposed method aims to improve the accuracy and reduce complexity of the FE-VBPM calculation by using the transverse vectorial FE-BPM with rectangular nodal element. The adaptive Padé approximation has been included in the wide-angle formulation. The simulation results include the coupling between two parallel rectangular optical waveguides.
