TLDR
Tapered mode-selective couplers are shown to allow for ultra-broadband mode-division multiplexing of few-mode optical fiber as discussed by the authors, using appropriate three-core configurations, modes of arbitrary spatial orientation can be demultiplexed.Abstract:
Tapered mode-selective couplers are shown to allow for ultra-broadband mode-division multiplexing of few-mode optical fiber. Using appropriate three-core configurations, modes of arbitrary spatial-orientation can be demultiplexed. The successful fabrication of these wavelength-insensitive couplers would represent the realization of compact low-loss mode-multiplexers for use in high-bandwidth few-mode fiber networks.read more

Space-division multiplexing: the next frontier in optical communication
TL;DR: This paper focuses on SDM for fiber-optic communication using few-mode fibers or multimode fibers, in particular on the critical challenge of mode crosstalk, and presents the prospects for SDM in optical transmission and networking.

Survey and Evaluation of Space Division Multiplexing: From Technologies to Optical Networks
TL;DR: Results show that SDM fibers achieve a 1185-fold (18-fold) spectral-spatial efficiency increase compared with the 276-SMF bundle (single-core fiber) currently installed on the ground.

Capacity limits of spatially multiplexed free-space communication
TL;DR: In this article, the capacity limits of the orbital angular momentum multiplexing for free-space optical communication were revealed, and it was shown that it is not an optimal technique for realizing the capacity limit of a free space communication channel.

TL;DR: It is shown that 6×6 MIMO processing can be used to almost completely compensate for crosstalk and intersymbol interference due to mode coupling in a system that transmits uncorrelated 28-GBaud QPSK signals on the six spatial and polarization modes supported by a novel few-mode fiber.

Tapered single-mode fibres and devices. I. Adiabaticity criteria
TL;DR: In this article, two complementary delineation criteria are presented which provide guidelines to the design of relatively short, low-loss tapered fibres and devices, which are used to explain anomalous loss effects in depressed-cladding and W-fibres, as well as the difficulty in fabricating low loss devices by tapering such fibres.
