Radiation pressure is associatedwith themomentumof light, and it plays a crucial role in a variety of physical systems. It is usually assumed that both the optical momentum and the radiation-pressure force are naturally aligned with the propagation direction of light, given by its wavevector. Here we report the direct observation of an extraordinary optical momentumand forcedirectedperpendicular to thewavevector, and proportional to the optical spin (degree of circular polarization). Such an… CONTINUE READING
