Abstract
Novel boundary conditions based on Padé approxi- mations for the frequency domain two-dimensional/finite element (2-D/FE) simulation of planar optical junctions of arbitrary geom- etry and number of accessing waveguides are presented and de- scribed in detail. This efficient formulation is straightforwardly implemented within the 2-D/FE framework and also can easily be used in finite difference schemes. Three examples show the appli- cability and reliability of the present method: a waveguide step dis- continuity, waveguide transverse displacement and T-shaped beam splitter.
