Abstract
We propose a novel multiple-input multiple-output (MIMO) scheme over
multimode fiber, acting as a distributed random code generator fed by spatial
codes, using silicon photonics in the transmitter and maximum-likelihood (ML)
electronic detection in the receiver, providing an alternative to coarse wavelength
division multiplexing (CWDM) for implementation of ultrahigh speed parallel
transmission over short-range optical interconnects. The optical MIMO system
utilizes mutually coherent transmission and conventional direct detection
with one-bit quantization, facilitating cost-effective application to 100
Gb/s links over < 50 m.
