Abstract

An optical interconnection system for integrated circuits has an optical source that is split into at least two parts. One part is modulated and the other part is transmitted to a detector and input on the local oscillator signal in homodyne detection. A single source may be split many ways to provide a plurality of beams for modulating and a plurality of local oscillator inputs to separate detectors. Both inter and intra wafer connections are described.
