Abstract
Optical vortex, possessing an annular intensity profile and an orbital angular momentum owing to its helical wavefront, has been widely investigated in versatile applications, including a laser scanning microscope, optical telecommunication, and optical manipulation. In particular, optical vortex can twist an irradiated material, such as metal, silicon, polymer, and even liquid resin, to form spiral-shaped structured materials on the micro/nano scale [1-3]. The spiralling direction of such structured materials is controlled by the handedness of the optical vortex, i.e. the twisting direction of a helical wavefront. In recent years, a laser-indeed bacteria-waveguide, in which the optical radiation force collects cyanobacteria into the beam to form an optical waveguide [4], has been discovered.
