Refractive Index of Silicon and Germanium and Its Wavelength and Temperature Derivatives.

Abstract

Refractive index data for silicon and germanium were searched, compiled, and analyzed. Recommended values of refractive index for the transparent spectral region were generated in the ranges 1.2 to 14 micrometers and 100-750 K for silicon, and 1.9 to 16 micrometer and 100-550 K for germanium. Generation of these values was based on a dispersion equation which best fits selected data sets covering wide temperature and wavelength ranges. Temperature derivative of refractive index was simply calculated from the first derivative of the equation with respect to temperature. The results are in concordance with the existing dn/dT data.
