Paper Abstract

We induced grating structures in polymer films containing small liquid crystal droplets. The grating formation is due to the thermal effect of an intensity grating caused by the interference of two Ar-laser beams. A light-induced grating-like modulation of material properties is stored after the exposure. It can be erased by heating the hole sample. The diffraction efficiency of the grating can be modulated by external electric fields.
