Abstract

Purpose. Present work is devoted to the optimization of metal-dielectric waveguides for practical application in integrated optics.

Actuality and practical importance. Such waveguides are a perspective element for creation of variety devices of integrated optics (multichannel splitters, modulators and switches, the filters radiating structures etc.) in various units of integral-optical schemes.

Choosing of method. It is shown, that optimization of parameters of planar metal-dielectric waveguide can be performed using the values of phase and group velocities of propagating modes on fixed frequency when solving the return scattering problem on the basis of wave equations.

Conclusion. The method of return scattering problem solving that consists in restoration of differential operator from its spectral function make it possible to receive singlemode thin-film metal-dielectric waveguides having the expanded singlemode band regime and the increased cross-section sizes. For verification of results the model experiment with solving of direct problem for obtaining waveguides is executed.
