Abstract

With respect to the manufacturing of optical elements, facile and effective fabrication method is proposed. It is developed in connection with photo-induced surface relief (PSR) formation phenomenon that occurs on the azobenzene functionalized polymer film. Purely optically inscribed surface relief structures have been used as a plastic mold for manufacturing of its replica. At least a hundred times replication process has been achieved using thermosetting resin without any deterioration. This method has many merits not only from a technical viewpoint but also from a economical efficiency. In this report, first the PSR phenomenon is explained and then several examples for optical component fabrication are demonstrated. photo-induced surface relief (PSR), azobenzene polymer film, optical patterning, polymer mold (template), replication, thermosetting resin, UV curable resin, optical elements, kinoform, laser pattern generator.
