ABSTRACT:
Devices are optically interconnected on a large scale integrated circuit by fabricating gratings on optical sources that direct the light beams toward a reflecting surface. The reflecting surface is positioned a predetermined distance from the surface of the chip such that it reflects light beams from the sources toward detectors that are fabricated on or near the surface of the chip.
