Summary form only given. Parametric polariton scattering processes in semiconductor microcavities have been investigated intensively in the last years. These processes become accessible due to the characteristic curvature of the lower polariton branch. If polaritons are photoexcited at the inflection point of the branch, they undergo pair scattering in the excitonic section of the lower polariton branch. In the present experiments we advance further in this direction by tailoring the polariton dispersion, in order to obtain perfect control of the accessible scattering channels. For this goal two parameters can be adjusted: the geometrical dimensions of the resonator and the exciton-photon detuning.
