    AnnotationWe investigate motion of particle pairs optically bound in tractor beam. The tractor beam can exert a negative force on a scatterer, in contrast to the pushing force associated with radiation pressure, which can pull the scatterer towards the light source. The particle movements can be enhanced by long-range interaction between illuminated objects, called optical binding. We study optical binding of two micro-particles in various geometrical configurations and investigate their motional behaviour in tractor beam. We demonstrate that motion of two optically bound objects strongly depends on their mutual distance and spatial orientation. Such configuration-dependent optical forces add an extra flexibility to our ability to control matter with light. Understanding these interactions opens the door to new applications involving the sorting or delivery of colloidal self-organized structures.
