The use of the Rudolph-Neumann approximation at later stages of the derivation yields a waveguide dispersion formula much more accurate than previously published results. Material dispersion for an arbitrary dopant content is estimated by interpolating derivatives of the Sellmeier equation. Overall dispersion is thus predicted on an analytical basis.
