Transmission at 2×100Gb/s, over Two Modes of 40km-long Prototype Few-Mode Fiber, using LCOS-based Mode Multiplexer and Demultiplexer

Review of Space-Division Multiplexing Technologies in Optical Communications

“…A combination of optical discriminator and MIMO signal processing can distinguish higher order LP-modes that accommodate high data-rate coherent modulation. In an early trial, 2 × 2 MIMO with 100 Gb/s [73,74] and 6 × 6 MIMO with 56 Gb/s [75,76] were demonstrated. As a SDM-MUX/DEMUX, FSO is proposed in an early report.…”

Multi-channel mode converters based on in-line fiber modal interferometer

“…time, frequency, phase/amplitude and polarization) are already used in current single-core single-mode fiber communication system. Modedivision multiplexing in few mode fiber is one of the promising approaches in space-division multiplexing transmission technology that is considered for overcoming current limitation of the transmission capacity in a single mode fiber [3][4][5]. In the MDM system, the mode converter is required to convert the fundamental mode in standard SMF into higher order modes in FMF.…”

5 × 5 25 Gbit/s WDM-MDM

“…A number of multiplexing techniques for increasing the data capacity through a single optical fiber have been proposed comprising wavelength [11,12], polarization [13,14], phase [14], amplitude [15,16] and time dimensions [17,18]. An elegant approach that has attracted significant attention is mode division multiplexing (MDM) [19], realized by combining or separating modes at the multiplexer and demultiplexer for transmitting independent data streams.…”
