We have produced high quality amorphous Ge/SiO, superlattice films with periods ranging from 2 to 30 nm. Normal incidence optical spectroscopy is used to determine the effectivemedium absorption edge, identical in this geometry to the interband edge in the narrow band gap layers (Ge). The edge shows
