Paper Abstract

Measurements of the refractive index of semiconductor materials, both in wafer and in waveguide form, are presented. The technique used to this purpose is based on radiation coupling into the material by a prism; this method is used for the first time on semiconductors, by means of a silicon prism. Accuracy to the fourth decimal place is demonstrated, in favorable comparison to the best available data.
