Abstract
On the basis of a microscopic theory, in which the electromagnetic and electronic nonlocalities have been incorporated, dependence of the intersubband absorption on the number of quantum wells (QWs) is studied. Detailed numerical simulations show that changes in the number of wells, the angle of incidence, and the barrier thickness between adjacent wells can significantly modify the radiative coupling among QWs. Consequently, the intersubband absorption spectrum can also be changed
