Physica Status Solidi (a), 1971
The refractive index of GaN and its temperature dependence have been measured using plane-parallel platelets with E ⊥ c. In this direction at 300 K the index is 2.67 at 3.38 eV, 2.33 at 1.0 eV, and has an extrapolated value of 2.29 ± 0.005 at 0 eV. The difference in the refractive indices for E ⊥ c and E ‖ c is 1.5 ± 0.2% at 5000 A. A Debye temperature

Conversion of group refractive index to phase refractive index
Journal of the Optical Society of America A, 1988The so-called group index of refraction may be measured by observing the shift of the visibility envelope when a sample is inserted into one arm of a Twyman–Green interferometer. Although the group and phase index curves are related, the phase index cannot be directly calculated from the group index because there are infinitely many phase index curves ...

Applied Optics, 1971
The refractive index of silicon was measured at room temperature over the range 1.1-2.0 micro by autocollimation in an ~12 degrees wedge. The image was observed by sweeping it across a slit in front of a lead sulfide cell whose output was displayed vertically on an oscilloscope while the sweep frequency was displayed horizontally.

Refractive Index Measurement of High Refractive Index Glass Beads
Applied Optics, 1975The refractive index of a small sphere and rod was measured by a method using the theory of rainbow that the minimum deviation angle of a single internally reflected ray from a sphere depends solely on the relative refractive index of the sample to the medium. Experimental results confirmed an accuracy of about 1%. This method is particularly suited to
