Refractive index and material dispersion interpolation of doped silica in the 0.6-1.8 mu m wavelength region

An extension of the Claussius-Mossotti interpolation scheme is proposed so that the refractive index and material dispersion of GeO/sub 2/- and F-doped silica glasses (with doping concentrations different than those of published data) can be predicted in the 0.6-1.8- mu m wavelength region. The new interpolation expression provides a well-behaved functional relationship for use in computer models which analyse propagation in single-mode fibers. The technique proposed is particularly powerful because it can be applied to any glass, whether single or multicomponent, having any other single dopant.>
