Abstract: A method of manufacturing an optical film includes providing a base film. The base film includes a substrate defining a first surface and a second surface. The base film also includes a plurality of structures defining an upper surface and at least one side surface extending from the corresponding upper surface to a base portion. The method also includes depositing a catalyst material on each of the plurality of structures and the base portion to form a catalyst layer thereon. The method further includes selectively removing the catalyst layer from the upper surface of each of the plurality of structures and the base portion while retaining an activity of the catalyst layer on the at least one side surface of each of the plurality of structures. The method includes forming a metallic layer on the at least one side surface of each of the plurality of structures.
