Abstract

Light-induced anchoring of the molecular director is reported to be an efficient method for writing permanent holographic gratings in dye-doped liquid crystals. We have achieved higher sensitivity and spatial resolution in these materials with other methods. An energy density as low as 10(-1) J/cm(2) was sufficient to write gratings with a resolution higher than 100 lines/mm.

摘要

据报道，光诱导分子指向矢的锚定是在染料掺杂液晶中写入永久全息光栅的一种有效方法。我们用其他方法在这些材料中实现了更高的灵敏度和空间分辨率。低至10(-1) J/cm(2) 的能量密度就足以写入分辨率高于100线/毫米的光栅。
