abstract = {We report two-dimensional localization of exciton polaritons in a
coherently pumped planar semiconductor microcavity operating in the
strong-coupling regime. Two-dimensional polariton solitons exist
despite the opposite dispersion signs along the orthogonal in plane
directions. Nonlinearities compensating the opposing dispersions
have different physical origins and are due to the repulsion of polaritons
on one side and due to parametric four-wave mixing on the other.
Both of these nonlinearities can support their respective families
of one-dimensional solitons, which coexist with each other and with
the two-dimensional solitons.},
