Abstract

We demonstrate the formation of chiral surface structure of azo-polymers via optical vortex induced two-photon-absorption (TPA). TPA-induced isomerization allows us to create the threedimensional chiral structures with high longitudinal and transverse spatial resolution beyond the diffraction limit.
