Nanostructures creation by optical angular momentum transfer

摘要

Optical vortex carries an orbital angular momentum together with a spin angular momentum, and it enables us to establish various nanostructures (e.g. chiral nanoneedles, chiral polymeric reliefs, monocrystalline silicon needles) by orbital angular momentum transfer effects. Such nanostructures fabricated by optical vortex illumination will explore new materials sciences technologies, including plasmonic metasurfaces for chiral sensitive imagers and chiral chemical reactors, and bio-MEMS.
