Abstract

We demonstrate the usefulness of the recently introduced modified Padé approximant operators for the solution of time-domain beam propagation problems. We show this both for a wideband method which can take reflections into account, and for a split-step method for the modeling of ultrashort unidirectional pulses. The resulting approaches achieve high-order accuracy not only in space but also in time.
