Abstract :
In this paper, a three-dimensional wide-angle beam propagation algorithm based on Pade series expansion is presented for photonic integrated circuits and devices. This offers an extra degree of freedom within configuration when applying BPM´s in the design of general photonic integrated circuits incorporating angled waveguide sections. The present wide angle beam propagation technique is compared with the conventional wide angle BPM through numerical examples in 3D dielectric waveguide and curved 3D waveguide model
