Temperature Dependence of the Index of Refraction of Fused Silica
arXiv:cond-mat/9712327 · doi:10.1119/1.18711
Abstract
In order to explain the positive temperature coefficient of the visible index of refraction of fused silica I develop a simple model which assumes a single ultraviolet resonance. Assuming thermal broadening and using the Kramers- Kronig relations leads to a temperature coefficient in qualitative, but not quantitative, agreement with measurement.
