Abstract

The multiple diffraction of waves in a one-dimensional periodically modulated medium is studied with a new perturbation method. A simple diagram calculus yields the coupling coefficients between the modes to an arbitrary number of diffractions. Applications of the method to several model grating profiles show new effects such as band-gap “disappearance,” shift in the dispersion spectrum, and controlled transmission. An optical switching device based on multiple diffractions is described.
