Abstract

The application of patterned photoalignment of reactive mesogen by a novel alignment of a polymer to create anisotropic diffraction gratings is demonstrated. It is shown that the weak sensitivity of the photoinduced surface anisotropy of the aligning layer to additional UV exposure greatly simplifies the procedure of grating formation. Anisotropic diffraction is investigated experimentally, and the results are confirmed by theoretical simulation.
