Comparison with a viscoelastic analysis shows that, for a step-index optical waveguide, the "fluid core" assumption provides a better approximation to the thermal stresses than the "elastic core" assumption. In this paper, we present an analysis of the stresses in a graded-index fiber, based on the fluid core assumption. A more realistic estimate of the setting temperature is also provided. The influence of the calculated stresses on the refractive index profile is shown to be significant.
