Abstract:
A method of optically interconnecting integrated circuits, comprising:forming a plurality of optical waveguides having a first coupling element and a second coupling element onto a printed circuit board; electrically coupling opto-electronic transmitters and receivers to integrated circuits, said integrated circuits being bonded to substrates, said substrates being bonded to the printed circuit board, the opto-electronic transmitters and receivers being aligned correspondingly with the first coupling element and the second coupling element of the plurality of optical waveguides; modulating light emissions of the opto-electronic transmitters with electrical signals from the integrated circuits to form divergent modulated light emissions; emitting divergent modulated light emissions; collimating divergent modulated light emissions of the opto-electronic transmitters using attached lens to form collimated modulated light and directing the collimated modulated light toward the first coupling element; receiving, by the first coupling element, the collimated modulated light and forming propagating modulated light; transporting the propagating modulated light from the first coupling element through the optical waveguides to the second coupling element; directing the propagating modulated light from the second coupling element toward the corresponding lens attached to the opto-electronic receivers to form modulated light emissions; and transducing, by the opto-electronic receivers, the modulated light emissions into electrical signals for the integrated circuits.
