Abstract
An efficient wide-angle beam propagation method based on Denman-Beavers iterative scheme for tilted optical waveguides is proposed, where the beam is shifting along the propagation. By shifting the beam opposite to the variation of the waveguide geometry in every step, the propagation in a longitudinally varying waveguide is realized through an equivalent straight waveguide. Significant improvement in efficiency with almost no influence on the accuracy is achieved.
