This paper presents a novel split-step time-domain beam-propagation method (TD-BPM) for simulation of time-domain pulse propagating in optical waveguide devices. Different from the traditional methods, where the time-marching step is strictly limited by the relation Δt=Δz/vg, the new split-step algorithm allows much more relaxed temporal and spatial steps, and therefore is much more efficient.
