Abstract: 
In this work the linear and nonlinear optical properties of ZnSe based heterostructures in the spectral range of polaritonic resonances are experimentally and theoretically investigated. The transmission spectra of the series of high quality ZnSe/ZnSSe heterostructures are analysed in the linear optical regime with respect to the polariton modes occurring due to the k-quantization. The influence of coherent optical nonlinearities on polariton effects is studied. The coherent manipulation of the polaritonic system in ZnSe/ZnSSe heterostructures is performed in pulse-transmission and FWM experiments. It is shown in time-resolved pulse transmission that the polariton modes, their quantum beat structure, and the radiative decay can be coherently manipulated. The coherent control of polaritonic FWM polarization in both diffraction directions is explained in terms of the two-polariton coherences and of Pauli blocking.
