Abstract
We successfully created helical microfibers by irradiating picosecond optical vortex pulses with a wavelength of 532 nm to ultraviolet curing resin via a two-photon-photopolymerization process. Permanent refractive index change of resin caused by laser triggers the self-focusing of light and forms the Light-induced self-written waveguides. In this process, the orbital angular momentum of the light is transferred to make a helical microfiber. The resulting helical microfibers exhibited a length of ∼300 μm. Also, we can control the direction of twists by changing the sign of the topological charge of optical vortex.
