Abstract
The paper presents a simple coupled mode model to describe near band-edge phenomena in the spectral response of waveguides with a section containing a rectangular grating. It is shown that nearly all relevant parameters can be determined in reasonable approximation from only the dispersion curve and one adjustable, proportionality constant. The theory is compared with results from numerical calculations and experiments.
