MIMO-based mode-division multiplexed transmission over multimode fibers

Abstract

Abstract-We present results of combined mode-and wavelength multiplexed transmission over conventional graded-index multimode fibers. We selectively couple and receive up to 6 spatial modes of multimode-mode fibers with 3 and 6 and 45 spatial modes using photonic-lanterns based mode-couplers. The transmitted signals are recovered using MIMO digital signal processing.
