  In this paper we bring up our investigation on the properties of asymmetric
scattering in graphene made with the microcavity exciton-polaritons. It is
shown by numerical simulations of Gross-Pitaevskii equation that ratchet
phenomena occurs in the polariton graphene due to its structural inhomogeneity.
Thus, we suggest a way to induce preferential motion of polaritons by the
confinement potential engineering.
