Abstract

We report on a new coherent phenomenon in semiconductor microcavities at polariton selective resonance excitation by two femtosecond pulses, propagating along k₂ and k₁, associated with exciton gratings, travelling in lateral direction ± (k₂ - k₁). Diffracted polaritons experience a frequency shift as observed in nondegenerate spectrally resolved transient four-wave mixing experiments.
