As integrated circuit interconnect dimensions shrink, interconnect performance degrades due to increasing resistance. In addition, several other issues remain with metal interconnects, such as power consumption, cross-talk, and resistivity increases due to size effects. On-chip optical interconnects are a possible future solution to these scaling issues because they offer the promise of decreasing the interconnect delays while providing higher bandwidth to keep pace with the transistors, while potentially lowering power consumption and being immune to cross-talk.
In this talk, the justification
for optical interconnects will be presented and progress on the major on-chip
optical building blocks will be reviewed. It will be shown that significant
progress has been made on waveguides, detectors, and couplers. However, there
are still major challenges in the high speed electrical to optical conversion.
