“…Longer distance data transmission in FM-MCFs has also been reported-the best result to date being 20 WDM channel 40 Gbit/s polarization-division multiplexing (PDM)-quadrature PSK transmission over 527 km of FM-MCF supporting 12 cores, each guiding 3 modes (i.e. 36 SDM channels) [24].…”

Lightwave communications is a necessity for the information age. Optical links provide enormous bandwidth, and the optical fiber is the only medium that can meet the modern society's needs for transporting massive amounts of data over long distances. Applications range from global highcapacity networks, which constitute the backbone of the internet, to the massively parallel interconnects that provide data connectivity inside datacenters and supercomputers. Optical communications is a diverse and rapidly changing field, where experts in photonics, communications, electronics, and signal processing work side by side to meet the ever-increasing demands for higher capacity, lower cost, and lower energy consumption, while adapting the system design to novel services and technologies. Due to the interdisciplinary nature of this rich research field, Journal of Optics has invited 16 researchers, each a world-leading expert in their respective subfields, to contribute a section to this invited review article, summarizing their views on state-of-the-art and future developments in optical communications.

“…On the other hand, after the recent rapid development of mode division multiplexing transmission, LP mode notation has been widely used in many ultra-large capacity long distance transmission experiments [4,5,6]. This is because the MIMO-DSP can reproduce the input channel by itterative numerical calculation, even though the output channels are mixed together.…”

The evolution of electromagnetic field profile of LP modes along with the propagation owing to the difference of propagation constants between constituent true eigenmodes is accurately analyzed. It is shown that the mode demultiplexer can't accurately discriminate the LP mode at the output end and so the MIMO-DSP is inevitable for the mode division multiplexed transmission using LP modes. From the accurate analysis, a transform matrix between LP modes and constituent true eigenmodes is derived and a novel method to configure true eigenmode multi/demultiplexer is proposed to realize MIMO-free transmission.

“…More recently, even few-mode, multi-core fibers (FMMCFs) have been demonstrated as a combination of the two fibers to further increase the transmission capacity [28], [31]. The major new components for SDM are SDM multiplexers (SDM-MUXs) to couple light from different cores or different modes into SDM fibers, SDM fibers, SDM optical amplifiers to amplify SDM signals, SDM demultiplexers (SDM-DEMUXs), optical connectors/splicing as illustrated in Fig.…”
