Using the Burt-Foreman envelope function theory and an eight-band k p model, we have extended our previous work on optical transitions in InAs/GaSb quantum wells grown along the  direction by completing the interface Hamiltonian with the inclusion of its nonrelativistic part. We found a substantial contribution of the nonrelativistic term to the originally forbidden spin-flip optical transitions. However, this nonrelativistic term produces only a minor modification of the lateral optical anisotropy. © 2008 The American Physical Society.
