Abstract
An integrated circuit is presented in which optical signal propagation replaces or supplements conventional electrical signal propagation. Optical lasers, waveguides, beam splitters, and photodetectors are fabricated on top of or below conventional electrical semiconductor circuits to propagate data, clock, and control signals. Such optical signal propagation is generally more rapid than electrical signal propagation, and can free conventional electrical semiconductor circuit area by eliminating at least some conventional data busses and global clock and control wiring. Furthermore, optical clock signal propagation substantially eliminates clock skewing problems and reduces power consumption by significantly eliminating clock signal re-buffering.
