Electrically switchable two-dimensional penrose quasi-crystal
We present the fabrication of a quasi-crystal liquid crystal polymer morphology using holographic polymer dispersed liquid crystal (H-PDLCs). By interfering five coherent, laser beams on a liquid crystal polymer mixture, a quasi-crystal morphology cart be created on the mesoscale. We present scanning electron microscope (SEM) images mapped onto the calculated irradiance profiles confirming the quasi-crystal structure. Diffraction and electro-optic data are presented in the context of potential photonic applications.
