The spectral dependence of linear/circular dichroism in two-photon absorption is calculated for several zinc-blende semiconductors, using the four-band Kane bandstructure model. It is demonstrated that the incremental dichroism is highly sensitive to the details of the chosen band model, and particularly that the split-off valence band can have a major influence on its value. © 1994.
