Paper Abstract

We develop a novel design of diffractive optical elements fabricated by an electron-beam lithography for free-space optical interconnection. This element is synthesized by multi-functional computer-generated holograms with the over- write grating. Diffractive optical elements including Fraunhofer and image type holograms have been fabricated. The concept and the fabrication process of this element are presented.
