Abstract
An improved wafer-wide optical bus interconnect is described for use in wafer-scale integration systems. By optically coupling sub-systems on the wafer, faults normally found in electrically based interconnection topologies are avoided. The invention incorporates a planar waveguide which couples emitters and detectors distributed throughout the wafer. The waveguide transmits an omnidirectional emission from an optical diode to all detectors on the wafer. The only electrical connection between sub-systems on the wafer may be for power.
