In this paper, we study the optical Stark effect of excitons in InAs/GaAs quantum wells using renormalization wavefunction formulation. We investigate the absorption spectrum of excitons in an infinite quantum well model under the effect of a strong pump laser resonant with two electron quantized levels. We also deduce the dependence of the absorption probability on the well width and the pump laser detuning.
