Abstract

We report the observation of exciton blue shift in a DC- biased GaAS single quantum well with off-resonant pumping which is distinguished from the ac Stark shift by polarization selective pump probe spectroscopy with small detuning condition. This blue shift is interpreted as a result of internal field screening by virtual excitons.
