We assume that a photon of a given circular polarization promotes an electron-hole pair (exciton) creation with a well-defined spin orientation such that only linearly polarized light can generate biexcitons, cf., L. Jacak, P. Hawrylak, and A. Wojs, Optical Properties of Semiconductor Quantum Dots (Springer, Berlin, 1997).

The contributions of cubic and quadratic nonlinearities to the polarization can be roughly estimated as 𝒫(3)/𝒫(2)~χeff(3)ℰm/χeff(2)~5×10−2, using χeff(3)≃10−18m2/V2 for GaAs. Here the peak field amplitude ℰm of a picosecond 2π input pulse was estimated using the known pulse area as ℰm ∼ πh̄/degτp. Thus quadratic nonlinearities indeed dominate in our case.

In the circular polarization basis, the Bloch equations are exact such that no rotating wave approximation is needed.
