A year''s worth of developmental accomplishment in optical computing hardware materials and interconnection array configurations is evaluated. Attention is given to an optically interconnected 3D computer architecture, the features of programmable and reconfigurable interconnections, and the accomplishment of interconnect reconfiguration via the photorefractive effect and optical disks. Lead lanthanum zirconate titanate material has been used due to its comparative developmental maturity, producibility, and dynamic range.
