Abstract
We study the effect of pseudospin precession of exciton-polaritons, known as optical spin Hall effect, on the dynamics of polariton solitons in semiconductor microresonators operating in the strong-coupling regime. We demonstrate that elliptically polarized polariton solitons, coherently driven by a linearly polarized pump, can form robust bound states. Due to spin-to-orbital angular momentum conversion, these polariton soliton molecules move uniformly in the mirror plane provided transverse electric–transverse magnetic mode splitting is taken into account.
