Abstract
The optoelectronic interconnection of the present invention provides a means for interconnecting a plurality of integrated circuits and each having at least one termination. The termination includes a transmitting section and a receiving section. Each transmitting section includes means for converting an output electrical signal from the integrated circuit to an optical signal in the form of a beam and an output grating for emitting the optical beam from the integrated circuit. Each receiving section includes an input grating for receiving an input optical signal in the form of a beam, means for amplifying the optical signal and a photodetector for converting the optical signal to an electrical signal which is fed to the circuit. The integrated circuits may be mounted adjacent each other with the output signals being emitting from the integrated circuits in the same direction. A reflector is mounted over the integrated circuits to reflect an output signal beam from the transmitting section of one integrated circuit to the receiving section of another integrated circuit. Each of the transmitting sections is capable of varying the angle at which the output signal beam is emitted ther…
