Bleaching and related optical characteristics investigations have been carried out on near-infrared absorption bands in undoped, semi-insulating GaAs to examine the nature of As-rich defects relevant to the absorption. The results obtained for preferential bleaching characteristics have led to the conclusion that the defects responsible for the absorption are not likely to be isolated defects or a single species of simple associated defects.
