Abstract
Electromagnetically-induced transparency (EIT) is observed and analyzed for the group velocity of a femtosecond light pulse interacting with GaAs/AlGaAs multiple quantum wells (MQWs) in a transient regime. The calculated slowdown factor of the group velocity inside the medium due to the dynamic refractive index change is ~2.10 × 103. We discuss the potential of EIT-induced slow light in GaAs/AlGaAs MQWs for ultrafast (~210 GHz) all-optical information processing such as photon routing.
