Abstract

We report on the morphological, spectral and dynamical characterization of one-dimensional transmission holographic volume phase gratings, whose refractive index contrast and nanometric pitch are dynamically controlled by an incident laser light. The grating is obtained by the photo-polymerization of a recently developed photo-mobile holographic composite polymer material. The observed changes in the refractive index contrast and grating pitch strongly suggest that the reversible all-optical real-time modulation of the obtained diffraction efficiency is induced by nano-fluidics.

摘要

我们报告了一维透射全息体相位光栅的形态、光谱和动力学特性，其折射率对比度和纳米级间距由入射激光动态控制。该光栅是通过最近开发的光移动全息复合聚合物材料的光聚合获得的。观察到的折射率对比度和光栅间距的变化强烈表明，所获得的衍射效率的可逆全光实时调制是由纳米流体引起的。
