Abstract

It has been shown that electromagnetic fields carrying orbital angular momentum can twist the surface of an azobenzene polymer film, creating micro- and nano-scale structures. In this work, we have extended these calculations from vortex beams to vector beams by presenting an analysis of the induced-force density due to structured optical beams onto a dispersive-absorptive medium at two different regimes: paraxial and non-paraxial beams. From this, we have shown that it is possible to create much more complex patterns that could be of interest for nanostructuring azo-polymer surfaces.
