Paper Abstract

A numerical approach for three-dimensional optical waveguides using periodic boundary conditions in both transverse directions is presented. Expanding the electric and magnetic fields in a double Fourier series of complex trigonometric functions, Maxwell's equations are reduced to the eigenvalue problem of a linear system for the Fourier coefficients. The solutions yield the vectorial eigenmode fields for guided and radiation modes, both propagating in forward and backward directions. The method is used to analyze the junction of a fiber to an embedded waveguides and the power transfer between two parallel embedded waveguides.
