Abstract
An improvement has been made to Rouard's method for the analysis of fiber a nd waveguide gratings. The real reflectivity of each interface is used inst ead of an approximate value obtained by coupled-mode theory. The improved R ouard's method becomes a complete Rouard's method and an exact method. It i s simple and independent on coupled-mode theory for no calculation of coupl ing coefficient required. Numerical examples of uniform and nonuniform grat ings have been given.
