Unusual superhelix‐like patterns on the surface of azopolymer films (see Figure) have been directly photofabricated by exposure to a laser interference pattern. Each superhelix‐like pattern is aligned parallel to the others, with a diameter of micrometer scale that could be controlled by the laser interference periodicity.
