Abstract
We report on a new coherent phenomenon in semiconductor microcavities at polariton selective resonance excitation by two femtosecond pulses, propagating along k/sub 2/ and k/sub 1/, associated with exciton gratings, travelling in lateral direction +or- (k/sub 2/ - k/sub 1/). Diffracted polaritons experience a frequency shift as observed in nondegenerate spectrally resolved transient four-wave mixing experiments.
