Abstract
We predict that vortex dipoles nested in light beams trapped in graded-inde
x media can undergo closed Berry trajectories, yielding periodic vortex ann
ihilations and revivals along the light-propagation direction. The vortex r
evivals from vortex-free wave fronts are mediated by Freund stationary poin
t bundles that carry the necessary Poincare-Hopf indices. Vortex spiraling
and spontaneous generation of circular-edge dislocations are also found to
occur. (C) 2001 Optical Society of America.
