Abstract: | A fully vectorial Rayleigh--Ritz method for the eigenmode calculation of dielectric waveguides is presented. It uses the four
transversal field components and takes rational functions as an orthonormal basis. This formalism is especially useful near
the cutoff frequency and has been applied for the investigation of the polarization properties of the output waveguides in
integrated spot-size transformers.
