Photopolymerization is a powerful technique to create arbitrary micro-objects with high spatial resolution. Importantly, date all photopolymerization studies have been performed incident light fields planar wavefronts and solely exploited the intensity profile of beam. We investigate possessing orbital angular momentum, characterized by topological charge l. show both experimentally theoretically that, as consequence nonlinear self-focusing optical field, creates an annular-shaped vortex-soliton associated fiber, which breaks up into |l| solitons or microfibers. These microfibers exhibit helical trajectories chirality determined sign l due momentum field form bundle helical-microfibers. This research opens new application for our generated may applications in communications micromanipulation.
