Abstract
Based upon equivalent transmission line method, a perturbation analysis on the guiding properties of refractive-index gratings is presented. By numerical calculation, the leakage parameter α which influences the leakage energy into the diffracted orders due to the grating scatter, is achieved as functions of the grating parameters.
