Abstract

An experimental study of the optical Stark effect in ZnSe-based quantum wells using pump-probe spectroscopy is presented. The Stark shift at both the heavy-hole and the light-hole resonances is measured as a function of pump detuning for samples with different heavy-hole-light-hole separations. The coupling between the heavy hole and the light hole has to be taken into account to explain the observed dependence on the pump wavelength detuning and polarization of pump and probe pulses. For a range of samples the Stark shift behavior is characterized by the ratio of the detuning to the heavy-hole to light-hole separation; higher order Coulomb correlations play a prominent role when the ratio is less than 2.
