| 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. |
