A large depolarization shift indicates a strong nonequilibrium intersubband electron-electron scattering ({Γ}) in tunneling structure. For a far-infrared subband separation {Δ}{~}10 meV, the rate {Γ} scales with the upper-subband occupation and is never significantly reduced by screening. Despite this nonradiative decay a finite population inversion can be maintained. Finally, the applied bias changes the wave-function symmetry so as to cause a dramatic variation of the electron-electron scattering rate. {} 1996 The American Physical Society.
