Abstract
We develop the theory of linear and nonlinear grating superstructures, gratings in which the parameters vary periodically with position on t he scale of typically about 1 mm. Following earlier work in semiconduc tors, these have now been written in optical fibers. We develop the th eory by introducing a set of superenvelopes: envelopes of the usual en velope functions of the grating structure. We show that under very gen eral conditions these superenvelopes satisfy a set of supercoupled mod e equations, and that these equations have solitary wave solutions.
