Calculated dependencies of the dipole matrix element on the applied electric field. Squared modulus of the dipole matrix element | D_{(2,0)→(1,1)}|² versus the voltage drop eFa per quantum well for different values of the parallel component of the magnetic field B _∥  = 1 to 5 T. The calculation was performed for the 250-Å GaAs/Al_0.3 Ga_0.7As quantum well. The transverse component of the magnetic field is B _⊥  = 5 T.
