Optical transitions for the (001) Al0.3Ga0.7As/AlAs/GaAs double-barrier superlattices are evaluated by a semiempirical, tight-binding calculation. The oscillator strength between the hole and electron states confined in either Γ- or X-like well are investigated as a function of AlAs slab thickness....
