Interaction of strong single-cycle terahertz pulses with semiconductor quantum wells

By Danielson, J R1; Lee, Yun-Shik; Prineas, J P; Steiner, J T; Kira, M; Koch, S W

An experiment-theory comparison is presented to demonstrate terahertz-induced extreme-nonlinear transients in a GaAs/AlGaAs quantum-well system. The terahertz-pump and optical-probe experiments show pronounced spectral modulations of the light- and heavy-hole excitonic resonances. Excellent agreement with the results of microscopic many-body calculations is obtained, identifying clear ponderomotive contributions and the generation of terahertz harmonics.
