The refractive index (RI) and the peak position of the first overtone of the fundamental SiO 4-tetrahedron vibration mode, 2ν 3, have been studied as a function of fictive temperature. The materials used are synthetic silica glasses of type III (trade names: F310, F300 and F320), which ...
Figure 1: Refractive index (solid lines) and group index (dotted lines) of silica versus wavelength at temperatures of 0 °C (blue), 100 °C (black) and 200 °C (red). The plots are based on data from M. Medhat et al., J. Opt. A: Pure Appl. Opt. 4, 174 (2002). The re...

Silica glass with OH content around 1200 ppm was densified by hot isostatic pressing (HIP) to about 1%. The wavelength dispersion of the refractive index of the densified glass was measured in the region 0.238–1.71 μm. The wavelength dispersion is well explained by the three-term harmonic os...
A liquid crystal eutectic is reported that has refractive indices matched to silica at 25°C and 1.3 mmi with the n0 below that of silica and nc above. It is demonstrated that the refractive indices of the eutectic allow a polarization filter, operating at telecommunications wavelengths, to be...
This paper presents measurements of the refractive index of a hygroscopic silica aerogel block at several wavelengths. The measurements, performed with a monochromator, have been compared with different parameterisations for n(λ), in order to determine the best chromaticity law for the aerogel. Thi...
The wavelength dependence of the refractive index of GeO 2 and GeO 2 F -doped PCVD (plasma induced chemical vapor deposition) silica was measured with an overall accuracy of ± 6 × 10 5. A model has been developed for predicting the refractive index in the binary glass systems GeO 2 SiO...
refractive index varies from 1.55 to 1.40 (for its transparent range: 160nm to 3000nm). Because fused silica is optically stable and consistent, many use it as a reference or standard for spectroscopic measurements. The details of its refractive index temperature dependence are also wel...
