Abstract : This report covers progress for the period 5/1/91 4/30/92 on a jointly sponsored AFOSR/ONR grant to Rutgers University that supports research in architecture and design of digital optical computers. Progress for this reporting period includes the development of an interactive design tool for digital optical circuits, the development of optical interconnection methods, and an investigation into the architectural implications of reconfigurable optical interconnects. Prior to this reporting period, an emphasis had been placed on the Bell Labs style of digital optical processor, in which arrays of optical logic gates are interconnected in free space with regular patterns at the gate level. The computer-aided design (CAD) tools and the optical interconnection methods that we have been developing allow us to characterize tradeoffs between the complexity of the optical interconnects and the complexity of the computer architecture. We plan to spend the final year of the effort engaged in characterizing these tradeoffs, a few of which are described below in the Micro vs. Macro-Optics section. One tradeoff that is of particular interest is in how the regularity of the interconnects affect the complexity of the optics, and how the regularity affects the depth and breadth of the resulting circuits.
