Electrooptic gratings have been used in integrated optics to form deflectors, modulators, and switches by a number of researchers. Recently we demonstrated a correlator based on an array of such individually addressable elements in conjunction with a modulated surface acoustic wave (SAW).1 The device performed as predicted by theory, generating the correlation of two 32-bit binary words at a data rate of 17.5 Mbit/sec.
