Abstract

The laser field dependence of the intersubband optical absorption in a graded quantum well (GQW), under an applied electric field is calculated in the effective mass approximation. We have theoretically shown that, in the GQW structures, not only the 'dressed' potential but also the direction of the external electric field plays a very important role in the intersubband transitions.
