Abstract
Birefringence in single crystal GaAs due to the ▪ dependence (or spatial dispersion) of the dielectric constant has been measured from 0.95 μ to 1.8 μ. Considerable enhancement was observed as the absorption edge was approached. The observed temporal dispersion in the birefringence was found to agree well with the prediction of a 4-band model involving no adjustable parameters. Within a model a direct relation was found to exist between the frequency dependence of the spatial dispersion and the warping of the J = 3 2 valence bands.
