Abstract

The propagation dynamics of an optical vortex pair is experimentally confirmed to experience enhanced rotation in a self-defocusing medium. We measured this effect to be 3.5 times larger than in linear media. The enhancement is attributed to nonlinear refraction within the dark vortex cores, permitting the vortices to propagate as vortex filaments.
