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.
Journal ArticleDOI
Ultra-high-density spatial division multiplexing with a few-mode multicore fibre

TL;DR: In this article, the authors demonstrate the viability of spatial multiplexing to reach a data rate of 5.1 Tbit/s−1/carrier−1 on a single wavelength over a single fiber, by employing few-mode multicore fiber, compact three-dimensional waveguide multiplexers and energy-efficient frequency-domain MIMO equalization.
Journal ArticleDOI
Electronic post-compensation of WDM transmission impairments using coherent detection and digital signal processing.
TL;DR: A universal post-compensation scheme for fiber impairments in wavelength-division multiplexing (WDM) systems is proposed based on coherent detection and digital signal processing (DSP).
Journal ArticleDOI
Supermodes for optical transmission.
TL;DR: Through simulations, it is shown that the proposed coupled multi-core fiber allows lower modal dependent loss, mode coupling and differential modal group delay than few-mode fibers, and could be a good candidate for both spatial division multiplexing and single-mode operation.
Journal ArticleDOI
Recent advances in coherent optical communication
TL;DR: In this paper, a review of recent progress in coherent optical communication, a field revived by advances in digital signal processing (DSP), is reviewed, showing that DSP-based phase and polarization management techniques make coherent detection robust and practical.
