Abstract

A rigorous, full-vectorial and computationally efficient finite element-based modal solution, together with junction analysis and beam propagation approaches have been used to study bending loss, transition loss, mode coupling and polarization coupling in bent optical waveguides with vertical or slanted side walls. The waveguide offset and their widths have been optimized to reduce the transition loss and the mode beating.
