Abstract

We report an experimental demonstration of electromagnetically induced transparency in the transient optical response in a cascade-type three-level system of GaAs/AlGaAs multiple quantum wells, and analyze the cascade-type three-level schemes with density matrix and Maxwell equations to then obtain the phase shift, group velocity, and group-velocity dispersion. The calculated group velocity is ∼6.87×104 m/s and the corresponding pulse delay is ∼7 ps. Finally, we provide a convenient basis for investigating many-body effects in semiconductors.
