| Popis: | We use two-dimensional (2D) THz-spectroscopy to study the $\chi^{(3)}$ non-linearities originating from four-wave mixing (FWM) in a quantum cascade structure (QCS), embedded in a single-plasmon waveguide. This approach allows us to extract the strength of all system non-linearities, study time-resolved system properties such as population and coherence lifetimes, as well as identify the dominant scattering mechanisms of the unbiased QCS at 10K. |
