| Popis: | We present results of experimental work in which the coherent-control technique has been applied to study the coherent manipulation of excitonic polarization in ZnSe quantum-well samples. We will introduce the linear control of excitonic polarization in pulse-transmission experiments and afterwards focus on the question if and how the optical transition from the excitonic states to the bound-biexciton state can be subject to a directed coherent control. The experimental results will be compared to simulations based on a microscopic theory and will also be explained on the base of a phenomenological few-level model. The overall suitability of coherent control for the investigation of exciton systems in low-dimensional wide-gap materials will be discussed. |
