The intersubband optical absorption of a semiconductor quantum well driven by an in-plane terahertz electric field is investigated theoretically by employing the extended semiconductor Bloch equations. Our results show that in-plane polarized terahertz fields induce a variety of behavior in the absorption spectra, including terahertz replicas of the main absorption peak and the dynamical Franz-Keldysh effect. The dependence of the absorption of the probe field on frequency and phase of the terahertz field is also very remarkable.
