Abstract

Switchable holographic gratings are desirable for a wide range of applications in diffractive optics. Liquid crystalline materials look attractive for these devices because of their large field- induced birefringence. The combination of electro-optical liquid crystals with photopolymeric holographic materials offers a unique single system approach to the economical fabrication of switchable holograms. We report on the progress in our development of a novel system where holographic gratings are recorded in a single step process and consist of periodic polymer-dispersed liquid crystal planes. Gratings have been recorded with high diffraction efficiency (approaching 100%) and narrow angular selectivity (<1 degree(s) FWHM). The diffraction efficiency can be controlled electrically or thermally
