Abstract

A liquid crystalline optical medium includes polymer stabilized liquid crystal material. The polymer stabilized liquid crystal material includes a short pitch cholesteric liquid crystal material stabilized by a polymer material. The effective phase retardation of the polarization independent liquid crystal optical medium can be controlled by external (for example, electric and magnetic) fields.
