Abstract
A slab waveguide with an embedded non-linear grating is considered as an al l-optical power-limiting device. The limiting action is based on the power losses at boundaries between grating sections, where a mode-mismatch result s from the self-focusing of the fundamental mode in each non-linear section . Time-harmonic and optical pulse propagation are both modelled numerically by finite-difference techniques to demonstrate the behaviour of the device .
