Paper Abstract

A novel structure for an electro-optically controlled Fresnel phase zone plate is proposed. This structure consists of a liquid crystal layer, which takes a homogeneous alignment parallel to the glass substrate surface, and ITO (indium tin oxide) electrode layers on the inner surface of the two glass substrates are formed with the same odd and even zone pattern respectively by using photolithography technology. This kind of zone plate in principle gives nearly 100% diffraction efficiency, and its light gathering power can be electrically adjusted. The detailed fabrication process and primary experimental results are presented.
