ABSTRACT:
A new light modulating material using unidirectionally oriented micro-domains of liquid crystal separated by polymer chains is provided. Liquid crystal/polymer films are produced by a one step production process involving a photopolymerizable monomer mixed with a liquid crystal then exposed to UV light. In one embodiment, force deformations are applied to the films resulting in diffraction efficiencies of more than 95%. In another embodiment, applying a planar force to a thick film that produced a 2 μm shift of phase retardation in several hundred microseconds when an appropriate field is applied. Use of this invention provides fast response time and a low required driving voltage. The new cell can be used as spatial light modulators for manufacturing information displays, electro-optical devices, telecommunications system, optical data processing, adaptive optics applications, color projection displays and switchable micro-lens optics.
