Multidimensional processing: Nonlinear optics and computing

Abstract

Abstract. The purpose of this paper is to overview some of the trends and directions in computing, as pertbrmed by optical hardware, resulting from the demands made by mtfltidimensional signal processing. Optical information processing or opticaJ computing is a vast field and some of the more significant issues are discussed here. We discuss future developments and architectural consequences for such potentially highly parallel and interconnected processing systems. Particular emphasis is placed on energy and speed considerations, associated with the use of nonlinear optical materials in optical systems and devices.
