Microled parallel optical interconnects

A parallel optical interconnect assembly for optically coupling integrated circuits, comprising:

• a first optical transceiver array having a plurality of optical transmitters;
• the plurality of optical transmitters each having a drive circuit connected to a microLED;
• a multicore optical fiber configured to transmit light emitted by each microLED of the plurality of optical transmitters;
• a first optical coupling assembly to couple light to the first end of the multicore optical fiber, the first optical coupling assembly having a first refractive lens separated from the first optical transceiver array by a first distance equaling to a first focal length of the first refractive lens, a second refractive lens separated from a first end of the multicore optical fiber by a second distance equaling to a second focal length of the second refractive lens, with the first and second refractive lenses being separated from each other by a third distance equal to the first distance and the second distance combined;
• a second optical transceiver array having a plurality of optical receivers;
• each of the plurality of optical receivers having a photodetector connected to a receiver circuit;
• and
• a second optical coupling assembly having one or more refractive collectors configured to direct light transmitted from a second end of the multicore optical fiber to each photodetector of the plurality of optical receivers.
