| Abstract: | The variational method is proposed to analyze the influence of the fabrication parameters on the performance of buried K+–Na+ ion-exchanged Er3+–Yb3+ ions co-doped glass waveguide. The unknown parameters of the Hermite–Gaussian functions as the trial field distribution are
determined based on the scalar variational principle. It is demonstrated that the results calculated in this paper agree with
those measured in the experiment. The mode dimensions, the effective refractive index, and the overlap factor as the functions
of the fabrication parameters are investigated. These results of the variational analysis are useful for the design and optimization
of Er3+–Yb3+ ions co-doped waveguides. |
