Mode-Division Multiplexing Over 96 km of Few-Mode Fiber Using Coherent 6 $\,\times\,$ 6 MIMO Processing
R. Ryf,Sebastian Randel,Alan H. Gnauck,C. Bolle,A. Sierra,Sami Mumtaz,Mina Esmaeelpour,Ellsworth Burrows,R.-J. Essiambre,Peter J. Winzer,D. W. Peckham,Alan McCurdy,Robert Lingle +12 more
TL;DR: In this article, simultaneous transmission of six spatial and polarization modes, each carrying 40 Gb/s quadrature-phase-shift-keyed channels over 96 km of a low-differential group delay few-mode fiber, is reported.

TL;DR: Dual-comb distance measurements with Allan deviations down to 12 nanometers at averaging times of 13 microseconds along with ultrafast ranging at acquisition rates of 100 megahertz are demonstrated, allowing for in-flight sampling of gun projectiles moving at 150 meters per second.
Journal ArticleDOI
Broadband Information Broadcasting Using LED-Based Interior Lighting
TL;DR: In this article, the authors investigate analytically and by Monte Carlo simulations feasible data transmission rates in a moderate-size office room, where the use of commercially available LEDs and photodiodes.
Journal ArticleDOI
6×56-Gb/s mode-division multiplexed transmission over 33-km few-mode fiber enabled by 6×6 MIMO equalization
Sebastian Randel,Roland Ryf,A. Sierra,Peter J. Winzer,Alan H. Gnauck,Cristian Bolle,Rene-Jean Essiambre,David W. Peckham,Alan McCurdy,Robert Lingle +9 more
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.
Proceedings ArticleDOI
Visible light communications: Challenges and possibilities
TL;DR: The basic components in visible light communications systems are outlined, the state of the art is reviewed and some of the challenges and possibilities for this new wireless transmission technique are discussed.
