SWITCHABLE HOLOGRAPHIC GRATINGS |
摘要 |
<p>The present invention includes systems and compositions of holographic grating structures devices and methods for fabricating such holographic grating structures. The method comprises the steps of preparing a composite mixture comprising a polymerizable matrix, a liquid crystal, and a photo-oxidant dye, producing an interference pattern from two interference beams, wherein the two interference beams originate from a recording laser beam directed by a low energy laser, and projecting the interference pattern on the composite mixture to form a holographic grating structure. As described, the holographic grating structure yields a first-order diffraction efficiency of at least about 30% diffraction efficiency which may be adjusted by the application of an electric field.</p> |
