Propagation of an optical vortex in a curved space-time |
|
Abstract |
Recently, optical vortices, twisted light beams like corkscrew around axes of travel, are actively investigated in laboratories. The beams carry orbital angular momentum along their propagation axes. We study orbits of an optical vortex in a curved spacetime using the eikonal approximation. We show that the equation of motion for an optical vortex is different from the geodesic equation due to 'spin-gravity' coupling. We discuss deviation of orbits from the geodesic in a Kerr spacetime. |
