Abstract： We have theoretically investigated optical absorption spectra in GaAs quantum well (QW) driven by both a strong terahertz (THz) field and a near-infrared field within the theory of density matrix. In presence of a strong THz field, the optical transitions in the QW subbands are altered by the THz field. The alteration has a direct impact on the optical absorption and results in the Autler-Townes splitting and the sidebands generation, which is in agreement with the experiments.
