Abstract

Optical interconnection has been extensively studied and demonstrated recently as a new approach in massively parallel computers. In our proposed system, the dynamic reconfigurable interconnection is achieved by the novel application of a two-level holographic reconstruction system in which one level provides permanent holographic storage of the collection of interconnection fringe patterns as images, and the second level is a single hologram produced by the reconstruction of a fringe pattern image that was previously stored in the first level. A first level, a volume holographic storage medium such as photore-fractive material Fe:LiNbO₃ will be used to store a set of predefined interconnection fringe patterns as the lookup table hologram. At the second level, an erasable spatial light modulator with fast response time is employed to hold temporarily a fringe pattern image corresponding to a certain interconnection from the first level.
