We propose the application of computer-generated Fourier domain holograms to wavefront synthesis and manipulation in integrated optics. In particular, we describe the use of such diffractive optical elements to split a guided plane wave into several equal-intensity output waves. Gratings with fan-out to 6, 7, and 8 are demonstrated with about +/- 25% (approximately +/- 1 dB) array uniformities.
