Description
Summary: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 approximately 2.10 x 10(3). We discuss the potential of EIT-induced slow light in GaAs/AlGaAs MQWs for ultrafast (approximately 210 GHz) all-optical information processing such as photon routing.
