title: Designing digitial optical computing systems: power distribution and cross talk.
abstract: Complex optical computer designs must implicitly or explicitly allow for power budgeting to compensate for cross talk and loss both in devices and in interconnections. We develop algorithms for calculating the system cross talk and power loss in optical systems by using a graph-theoretic model. Devices are modeled as directed graphs with nodes that represent inputs and outputs, and edges are weighted with the power relationships between nodes. Systems are modeled by interconnecting the individual device graphs in a manner that reflects the connectivity of the system. A system's power budget is efficiently computed by a depth-first search of its graph. The algorithms have been incorporated in an optical computer-aided design system that is presently being used to design a bit-serial optical computer that contains hundreds of components.
