Diffraction Properties of Field-Adjustable Polymer Network Stabilized Liquid Crystal Grating
摘要
Abstract
A new diffraction grating mode has been proposed. This grating is formed by applying of a spatially periodic electric field to a polymer network stabilized uniformly aligned liquid crystal layer. Due to the electro-optic properties of the polymer network stabilized liquid crystal layer, the grating type is electrically adjustable, i.e. it presents amplitude, phase or amplitude-phase type depending on the applied voltages. Experimental results show that the number of visible diffraction orders can be adjusted easily, and even be closed at the same time. The detail fabrication process and experimental results will be presented.
