Abstract
Linear photo-oriented polymer (LPP) layers are situated to align liquid crystals in a liquid crystal polymer (LCP) layer situated at or on the LPP layers. The LCP layer can include a guest such as a fluorophore that aligns with the liquid crystal so as to emit polarized fluorescence in response to an excitation beam. Layer LPP/LCP structures can be provided as light emitters, patterned polarizers, patterned retarders and other devices based on selection of one or more guest materials included in the LCP and alignable with the liquid crystal.
