1. An optical link for data communications between optical transmitters and optical receivers, comprising:
an optical transmitter array having a plurality of microLEDs and each microLED configured to generate light;
an input array optical coupling assembly having one or more lenses and/or mirrors for relaying light from each microLED;
a coherent fiber bundle having a plurality of cores, the coherent fiber bundle having an input face opposite to an output face and the input face configured to receive light from each microLED that are relayed by the input array optical coupling assembly to reproduce said light at the output face as spatially-sampled at the input face
an output array optical coupling assembly having one or more lenses and/or mirrors; and
an optical receiver array having a plurality of photodetectors configured to receive light relayed by the output array optical coupling assembly from the output face of the coherent fiber bundle;
wherein each microLED of the plurality of microLEDs of the optical transmitter array is coupled to a single core of the plurality of cores of the coherent fiber bundle at the input face; and
wherein each photodetector of the plurality of photodetectors is coupled to a single core of the plurality of cores of the coherent fiber bundle at the output face.
