In our experiment, we observed a change in the angle of emission of the photons when injecting electrons to the system, which indicates that the interaction of electrons with the polaritons changes the momentum of the polariton condensate. The condensate flow was accelerated when electrons flow with the same direction, while the condensate was slowed down when electrons flow in the opposite direction. Because the experiment is a photon-in, photon-out system, this is equivalent to steering photons using a DC electrical current. A theoretical model is also built to describe the effect.
