We present theory and data for the valence-band structure for lattice-matched, strained, symmetrically- and asymmetrically-doped quantum wells (QW's). Our self-consistent k•p calculation using a plane-wave basis (PWB) yields accurate results and can be applied to arbitrary potential profiles. The PWB is convenient for shallow as well as type 2 QW's (with the light-hole QW inverted due to strain). Excellent agreement is obtained between the theoretical dispersion curves and the data.
