Abstract

We present the first demonstration of the 2-dimensional fabrication of surface reliefs with spiral two-, four-, and six-arms, named "galaxy-shaped surface relief," in an azo-polymer film by employing petal-like modes formed of the superposition of positive and negative Laguerre-Gaussian modes. This demonstration provides new physical insights into the interaction of light and matter to develop rewritable optical data storage with ultrahigh data capacity.
