Interference of coherent polariton beams in microcavities: polarization-controlled optical gates

Leyder, C., Liew, T.C.H., Kavokin, A.V., Shelykh, I.A., Romanelli, M., Karr, J.P., Giacobino, E. and Bramati, A. (2007) Interference of coherent polariton beams in microcavities: polarization-controlled optical gates Physical Review Letters, 99, (19), 196402-[4pp].

Record type: Article


We demonstrate, theoretically and experimentally, a polarization-controlled optical gate based on a degenerate polariton-polariton scattering process occurring in semiconductor microcavities. Because of the interference between coherent polaritons, this process is observed in the case of polaritons generated from two collinearly polarized coherent pump beams. On the contrary, if the beams are cross polarized, the scattering is suppressed.
