Paper Abstract

Using semiclassical time-dependent perturbation approach, we have analyzed one of the important optical coherent transient effects viz., the Stark shift and Stark broadening (also known as self energy correction) by incorporating the higher excitonic states in GaAs/GaAlAs quantum well structures irradiated by an ultrashort pulsed laser. It has been found that both Stark shift as well as Stark broadening get modified when we take into account multiple excitonic states.
