Comparison of optical properties between (100) and (111) superlattices of CdTe/(Cd,Mn)Te of similar Mn concentrations (x>0.20) shows pronounced differences near the exciton ground-state energies. This contrast can be observed particularly in the photoluminescence and its excitation spectra at low lattice temperatures. Its origin may be due to dependences on crystalline direction of microscopic, strain-driven details at the heterointerfaces.
