Abstract

The applications and systems specifications for photonic integrated circuits (PIC’s) continue to grow. This places an increasing demand on the complexity and compactness of such circuits and necessitates the accurate analysis of curved, intersecting, branching and coupled guided wave structures and waveguide directional changes incorporating mirrors. To enable study of such configurations ’wide angle’ beam propagation methods (BPM) have been introduced [1-6] but these become less accurate as the angle the waveguide makes to the propagation direction specified in the simulation increases.
