FIG. 1.

(a) Group refraction index for optical frequencies. Experimental data are shown for GaP (squares) and ZnTe (triangles). Solid and dash lines present results from the model functions. (b) Refractive index spectra at THz frequencies. Experimental results for ZnTe (triangles) and GaP (circles). Model functions are solid lines.
