Paper Abstract

An efficient approach to design the structure of diffractive optical elements is presented. We have developed a novel vectorial diffraction method that the amount of memory consumption is almost free from the entire size of dielectric structure. In the process of the device design, we update the diffracted wave by adding groove patterns on the surface one by one so that the updated wave approaches to the desired one. The necessary memory for two-dimensional structure is only around 20 MB, and our method is sufficient with a desktop computer to perform an accurate designing even including the polarization characteristics.
