Abstract

Periodic structures in the form of optical and subwavelength gratings are formed as alternating slabs of polymer and polymer-dispersed liquid crystals in a pentaacrylate system. We analyze the physics of formation as well as the optical properties expected from these structures. Experimental confirmation of these concepts is presented. Possible electro-optical applications in devices are given.
