Comparison of modal dispersion curves obtained for the (a) symmetric and (b) antisymmetric ridge modes shows good agreement between the ANSYS simulations and MATLAB computations. Note that the y-axes in these plots have different scales.
(a) Modal dispersion curve for the fundamental symmetric mode of a 2 μm wide ridge in Si
(b) Modal dispersion curve for the fundamental antisymmetric mode of a 2 μm wide ridge in Si
