Computing coupling coefficients in transmission systems

Abstract

A numerical method for simulating realistic problems of mode coupling in optical transmission systems is described. The conclusion concerning waveguided propagation of the electromagnetic field in complex structures, selective mode excitation and the power transfer may become an important factor in designing and connecting devices used in optical signal processing. The numerical method is based on an extension of the `Orthogonal Collocation Method' to the case of coupled systems of differential equations with an infinite range of independent variables.
