The Gerchberg-Saxton phase retrieval algorithm results in a phase profile which varies continuously, which is extremely difficult to fabricate. Binary optics technology offers a viable solution to this fabrication problem. We describe a modified Gerchberg-Saxton phase retrieval algorithm which incorporates the binary optics fabrication process into the iterative loop. This algorithm is used to optimize the phase profile of a multilevel phase grating which achieves a 2-D Gaussian fanout. The surface-relief structure which practically implements this optimized phase profile was fabricated. The results of the fabrication process are summarized and the experimental measurements on the fanout element are presented.
