We studied the optical properties of GaAs/Al 0X35 Ga 0X65 As asymmetric double quantum wells at T 4X2 K and in the presence of in-plane magnetic fields up to 20 T. In an electric field F 8 45 kV/cm, electrons and holes are respectively confined in the wide and narrow well and form spatially indirect
