Abstract

Summary form only given. In this paper, we present coherent optical effects in a quantum well system with two electron subbands coupled by a pump laser. The Coulomb and light induced electronic renormalization is investigated with generalized density-functional theory. On the basis of the renormalized electron states, the absorption coefficient of a probe light beam is studied for intersubband transition by using a self-consistent field theory. Both the electromagnetically induced transparency (EMIT) and probe light amplification without population inversion are found
