An important diffraction problem in modern optics is to design gratings that are able to produce given output power distributions from a given input. In this paper the coupled multiwave diffraction approach, together with an optimization method, is applied to design gratings, which diffract one incoming beam into N output beams with a given power distribution. Several gratings have been designed. We show that by choosing the material parameters properly relatively simple continuous grating profiles having better diffraction characteristics than binary gratings or kinoforms can be found.
