Paper Abstract

The optical field diffracted through a simple circular aperture can produce optical tubular structures single-closed of twice-closed by choosing the suitable experimental conditions. An important characteristic of such structures on this way generated is that they have strong intensity gradients at their edges, making them appropriate structures for optical trapping of particles.
