1. Optical communication apparatus for an optically interconnected integrated circuit which includes circuitry for performing logic functions, comprising:
an array of microLEDs;
optical transmission channels, comprising a multicore fiber, to receive light from the array of microLEDs at optical transmission channel inputs and output light at optical transmission channel outputs, wherein a number of cores in the multicore fiber is different than a number of microLEDs in the array of microLEDs, wherein each optical transmission channel comprises multiple cores of the multicore fiber that are made from a rigid material, and wherein each microLED in the array of microLEDs is configured to produce light to be carried in a plurality of cores of the multiple cores of the multicore fiber in the optical transmission channels;
optical elements, including at least one lens, between the array of microLEDs and the optical transmission channel inputs to magnify and focus light from the array of microLEDs onto the optical transmission channel inputs; and
an array of optoelectronic receivers, wherein each optoelectronic receiver is optically coupled to receive light from one optical transmission channel output of the optical transmission channels.
