In recent years, many groups have been engaged in research and development related to optoelectronic devices. In particular, the interest for polarization holography has been growing because polarization holographic gratings can be used for various kinds of applications. These gratings have been fabricated by employing a photoalignment process. Recently, we have developed a new alignment process generated by photopolymerization with scanned light. In this study, we have fabricated holographic films by the alignment control of polymer structures. Moreover, we have achieved to generate two dimensional alignment patterns by the control of the irradiation pattern. We analyzed the optical properties of the fabricated polymer films.
