Paper Abstract

The optical response of semiconductor quantum wells is investigated theoretically to explain nonlinear transients generated via intense terahertz (THz) fields. A microscopic description of THz-induced interaction processes is developed while several numerical examples are presented to illustrate properties in a typical THz-pump and optical-probe configuration. The results identify signatures of the ac-Stark effect, ponderomotive contributions, and extreme-nonlinear dynamics.
