Abstract

The optimization of the characteristics of the electrooptic modulators can be carried out by choosing the dimensions and cross-section of the millimeter and optical waveguides. A rigorous method of solving the Maxwell equations for the open waveguides with intricate (arbitrary) cross-sections including metallic, dielectric and anisotropic media is proposed in this paper. The longitudinal components of the electric and magnetic fields in the case of uniaxial anisotropic media contain the logarithmical singularity. This fact leads to the solution of that problem by means of singular integral equations, the method is versatile to the cross-section shape. The method proposed this paper allows to vary the electrodynamic parameters of a media (including the dielectric and anisotropic losses) in the wide range.
