Paper Abstract

We study the ability of beams carrying mixed step-screw phase dislocations to guide and steer probe beams with nonzero transverse velocity. We report the first experimental demonstration of bright signal beam deflection by steering odd beams of finite length carrying such dislocation. The numerical simulations show that the beam deflection can be ruled by the geometry and orientation of the dislocation.
