Abstract
An intense coherent laser field couples two electron subbands in quantum wells. Using generalized self-consistent density functional theory, we study the nature of the Coulomb and light-induced electronic renormalization. We show electric-field-induced transparency and light amplification without population inversion of a weak probe beam in such a system. The effects of the pump field strength, electron density, and δ-doping position are investigated.
