Electromagnetically induced transparency and slow light in V-type three-level system of GaAs/AlGaAs multiple quantum wells

► We observe electromagnetically induced transparency in multiple quantum wells. ► A V-type three-level system of GaAs/AlGaAs multiple quantum wells is constructed. ► We theoretically obtain the disperison, absorption, and group velocity. ► We can get the group velocity as ∼9.31×104 m/s and delay time ∼as 6.5 ps.
