Magneto-optical investigations of a series of strain-balanced InGaAs/GaAlInAs coupled quantum wells are described, showing how changes in the strain within the InGaAs wells modify the conduction and valence-band dispersion curves. Large non-parabolicities in both bands are demonstrated by comparison

We present a detailed study of the polarization dependence of subband absorption and photoconductivity in Si/SiGe quantum wells. For samples with a hole concentration of p :2.8;10 cm\, both p-and s-polarized absorptions have been observed and transitions to several excited states are clearly identif
