A new method for measuring single-mode waveguide parameters: Two polarization measurements of guided and leaky modes
A new method for measuring single-mode wayeguide parameters is presented in this paper. Mode refractive indices of fundamental guided and leaky modes at two polarization states are measured lay the prism coupler, and single-mode waveguide parameters are determined from four corresponding mode equations. Its measuring accuracy is higher than that of measurements of pure guided modes. Single-mode glass waveguide parameters were measured toy this method, and its error sources were analysed theoretically.
