Abstract

A new beam propagation method (BPM) is developed based on a direct approximation to the propagator by its [(p - 1)/p] Padé approximant. The approximant is simple to construct and has the desired damping effect for the evanescent modes. The method is applied to a tapered waveguide for TM-polarized waves, based on the energy-conserving improvement of the one-way Helmholtz equation. Numerical results are compared with those obtained with other variants of the BPM. © 2002 Optical Society of America.
