Paper Abstract

Our recent development of a simple and reliable method to generate terahertz (THz) pulses with high intensities (equivalent to high electric field amplitudes) has paved the way for nonlinear optics in the THz regime. We present experiments on bulk n-type GaAs which give new insights into phenomena like Bloch oscillations and Zener tunneling in bulk semiconductors. Another novel development in this field is two-dimensional THz spectroscopy. Here, we present first experiments on intersubband transitions in GaAs/AlGaAs quantum wells.
