ResumoFabry–Perot cavities were used to obtain experimental values for the quantity (n−λ dn/dλ) near the absorption edge in GaAs at 2 K. Here n is the refractive index and λ is the wavelength of light. Using an adjusted Sellmeier-type equation, n and −dn/dλ were calculated as a function of wavelength at 2 K. These are the only available values of n and −dn/dλ for GaAs at 2 K of which we are aware.
