Abstract
Interest in optical logic systems has been revived recently for several reasons. One major reason is that optics provides a means for overcoming the communication bottlenecks which are beginning to limit the development of electronic systems both at the chip level and at higher levels. This stems from the fact that an optical system in effect processes a large number of independent parallel channels. However, in attempting to implement optical interconnection networks, one is quickly faced with the need to realize space-variant interconnections. In this paper we describe various means of achieving space-variant interconnections for optical logic systems. All of the techniques use computer-generated holograms (CGH) as combination beam-splitting and beam directing elements. The space-variance can be obtained with either a direct approach where a separate CGH element forms the interconnections for each logic element, or with a basis set approach which provides significant reductions in the CGH storage requirements. Examples of the different approaches are discussed.
