Observation of optical stark effect in InGaAs/InP multiple quantum wells.
01 January 1987
We report an experimental observation of a blue shift in the n = 1 heavy hole exciton line of InGaAs/InP multiple quantum wells resulting from a picosecond photoexcitation in the transparent spectral region. The temporal response of this shift follows the excitation and it is attributed to the optical Stark effect. The shift is about 0.19 meV for a 10MW/cm sup 2 intensity.
