Photoreflectance (PR) and photoluminescence (PL) has been measured on the set of four samples containing 12 periods of a GaSb and an AlInAsSb digital alloy with various average Al fractions, both 12nm thick. Using 8kp with envelope function approximation, PL and PR spectra are qualitatively explaine...
