Electroreflectance measurements performed in conjunction with absorption and photovoltage spectroscopy have allowed a determination of the modulation mechanisms that are responsible for the quantum confined Stark effect in a ZnSe-Zn0.75Cd0.25Se double superlattice. This study indicates that the modulation of the excitonic transitions in the two superlattices (E-1hh(1), E-2hh(1), and E-1hh(2)) are observed in the electroreflectance spectra. Due to the thermal effects of the photoexcited carriers the higher subband with a smaller exciton binding energy is more sensitive to the ac electric field.
