We have performed full-scale calculations of the optical properties of (001) HgTe-CdTe superlattices, of period ∼60 Å. We present the superlattice band gaps and oscillator strengths for the principal transitions as a function of HgTe layer width, in good agreement with experiment. The valence-band offset is 370 meV. Our results highlight the importance of the degree of localization of interface states in determining the optical properties of the superlattice.
