摘要：

We present the design, fabrication, and electro-optical properties of a switchable Penrose quasicrystal configuration in holographic polymer dispersed liquid crystal (H-PDLC) materials using a 5-beam hololithography exposure technique. The Penrose quasicrystal structure is confirmed through diffraction patterns and scanning electron microscopy (SEM); both show the expected tenfold symmetry. We also present electro-optic switching parameters of this quasicrystal structure and determine its index modulation to be 3x10(-3) using coupled wave theory. (C) 2005 American Institute of Physics.
