We describe the coupling of the quantum well structure with the electromagnetic field by using the nonlinear density matrix equations, in the two-subband approximation. We provide proper approximate analytical solutions to these equations that are used for the closed-form determination of the optical susceptibilities &lt;span class=&quot;equationTd inline-formula&quot;&gt;&lt;span id=&quot;MathJax-Element-2-Frame&quot;
