Strained-layer superlattices of InAsSb were grown with low densities of dislocations and microcracks for optical characterization to determine the suitability of these structures for infrared photodetectors. Infrared transmission measurements revealed absorption throughout the 8--12 ..mu..m region and extended to longer wavelengths than predicted from consideration of the tensile strain-induced band-gap shift in a type-I superlattice. We conclude that a type-II superlattice occurs in the InAsSb system for alloy compositions >60% Sb.
