This paper introduces our recent results on mode-division multiplexing transmission with MIMO processing. We have been studying coherent optical MIMO transmission systems and developing few-mode fibers to reduce the complexity of MIMO processing, for example, by using multi-step index fibers to control the differential mode delay (DMD) of the fibers and to compensate for the total DMD. We also investigated a transmission system using reduced-complexity MIMO processing. Finally, we review our latest 2×2 WDM-MIMO transmission experiments with low MIMO processing complexity.
