Abstract

An optimal design of a modified type multilevel phase kinoform is presented. Both phase value in each kinoform cell and coordinates of transition points are used as variables of merit function in the optimization of the multilevel phase kinoform. The simulation results show that this multilevel phase kinoform has higher diffraction efficiency and lower relative error than that of others, in which only phase value in each cell is used as variables of merit function during the optimization. Some parameters which affect fabrication of kinoform are also analyzed.
