Abstract: This invention relates to a novel class of halofluorinated acrylates and more particularly to chlorofluorinated or bromofluorinated acrylates characterized by a chlorofluorinated or bromofluorinated alkylene moiety with acrylate functions at both terminals. These chlorofluorinated acrylates may be photocured in the presence of a photoinitiator into transparent polymers useful as optical waveguiding materials.

Abstract: Des guides d'ondes optiquement actifs (optiquement non linéaires ou électrooptiquement actifs) sont formés par dépôt d'une couche d'une matière organique, en général une matière polymère, comprenant un ou plusieurs composants optiquement actifs, et en soumettant des régions prédéterminées de la couche à un rayonnement actinique pour modifier l'indice de réfraction de ces régions.
