Abstract
We have developed a nonperturbational treatment for the calculation of the optical susceptibility of semiconductors in the vicinity of the two-photon biexciton resonance, based on operatorial techniques. The analytical expression of the intensity-dependent dielectric function shows a two-photon polariton effect, which displays bistability when local-field considerations are included in the calculation.Keywords
