Abstract
Sharp transformations of polariton-polariton scattering patterns in a semiconductor microcavity with an increase in pump intensity are observed. These transformations are manifestations of nonequilibrium first-order phase transitions in a strongly driven multimode Bose system. The effect arises from the interplay between the bistability of the pumped polariton mode and the parametric instability in the nonlinear polariton system.
