英文摘要	the nonlinear optical absorption in a three-subband step asymmetric semiconductor quantum well driven by a strong terahertz (thz) field is investigated theoretically by employing the intersubband semiconductor-bloch equations. we show that the optical absorption spectrum strongly depends on the intensity, frequency, and phase of the pump thz wave. the strong thz field induces thz sidebands and autler-townes splitting in the probe absorption spectrum. varying the pump frequency can bring not only the new absorption peaks but also the changing of the energy separation of the two higher-energy levels. the dependence of the absorption spectrum on the phase of the pump thz wave is also very remarkable.
