Paper Abstract

A new method of calculation of binary-phase and quantized diffractive optical elements (DOEs) is proposed. The design uses a specific series expression for the quantized DOE transmission function and is based on the gradient search algorithm for the optimization of truncated series approaching the quantized complex transmission function. Fast designs of binary beam shapers and multiorder binary gratings with equal order intensities are reported with the efficiency in the range of 70 - 75% and the root-mean-square errors of 3 - 5%. The design of binary DOEs that transform the gaussian beam into Gauss-Hermite (0,1) and (1,1) complex amplited distributions is also presented.
