Splice Loss of Graded-Index Fibers: Accurate Semianalytical Descriptions Using Nelder-Mead Nonlinear Unconstrained Optimization with Three-Parameter Fundamental Modal Field
Figure 3
Variation of power transmission coefficients with the normalized angular offset for splicing of two identical single mode trapezoidal index fibers with (exact numerical results [10, 13]; results by our approximation; results based on Gaussian approximation [10, 13]).
