First Experimental Demonstration of VCSEL-based Real-Time End-to-End 11.25Gb/s Optical OFDM Signal Transmission Over 800m MMFs
Jianming Tang1, Emilio Hugues-Salas1, Xianqing Jin1, Roger Giddings1, Jinlong Wei1, Chang Shu1; 1School of Electronic Engineering, Bangor University, United Kingdom.
11.25Gb/s 64-QAM-encoded real-time end-to-end optical OFDM transmission over 800m OM2 MMFs with a power penalty of <1dB is experimentally demonstrated, for the first time, in simple IMDD systems employing un-cooled directly modulated 3.63GHz VCSELs.

Orthogonal Multipulse Modulation for Next-Generation Datacommunication Links
Jonathan D. Ingham1, Richard Penty1, Ian White1, David Cunningham2, Petter Westbergh3, Johan Gustavsson3, Åsa Haglund3, Anders Larsson3; 1Department of Engineering, University of Cambridge, United Kingdom; 2Avago Technologies, United Kingdom; 3Department of Microelectronics and Nanoscience, Chalmers University of Technology, Sweden.
Orthogonal multipulse modulation is demonstrated to allow ~30 Gb/s real-time transmission over multimode fibre using an 850 nm VCSEL. The scheme eases considerably component bandwidth requirements compared with conventional NRZ modulation.

Chromatic Dispersion Compensated Multimode Fibers for Data Communications
Denis Molin1, Marianne Astruc1, Pierre Sillard1; 1Draka Communications, France.
Chromatic dispersion of 50µm multi-mode fibers will ultimately limit the reach and/or the speed of data communications. We propose and validate a new criterion that quantifies how chromatic dispersion can be compensated by modal dispersion in specifically designed fibers.

30 Gbps 4-PAM transmission over 200m of MMF using an 850 nm VCSEL
Krzysztof Szczerba1, Petter Westbergh1, Johan Gustavsson1, Åsa Haglund1, Johnny Karout2, Magnus Karlsson1, Peter Andrekson1, Erik Agrell2, Anders Larsson1; 1Photonics Laboratory, Department of Microtechnology and Nanoscience, Chalmers University of Technology, Sweden; 2Department of Signals and Systems, Chalmers Univeristy of Technology, Sweden.
Real time, error free 4-PAM transmission at 25 Gbps and 30 Gbps over 300 m and 200 m of multimode fiber, respectively, using a VCSEL operating at the wavelength of 850 nm.

Simultaneous Transmission of Wired and Wireless Services over Large Core POF for In-Home Networks
Yan Shi1, Davide Visani2,1, Chigo M. Okonkwo1, Henrie H. Boom, van den1, Giovanni Tartarini2, Eduward Tangdiongga1, Ton Koonen1; 1COBRA Research Institute, Eindhoven University of Technology, Netherlands; 2Dipartimento di Elettronica Informatica e Sistemistica (DEIS), University of Bologna, Italy.
Broadband wired and wireless signals are simultaneously transmitted over 1mm core size 50m POF and 2.5m air link. 3 Gbit/s DMT and 480 Mb/s UWB are successfully delivered with BER <10-3 and EVM <15%, respectively.

12.5 Gbps Indoor Optical Wireless Communication System with Single Channel Imaging Receiver
Ke Wang1, Ampalavanapillai Nirmalathas1, Christina Lim2, Efstratios Skafidas1; 1Department of Electrical and Electronic Engineering, National ICT Australia-Victoria Research Laboratory (NICTA-VRL), The University of Melbourne, Australia; 2Department of Electrical and Electronic Engineering, The University of Melbourne, Australia.
In this paper we propose a novel single channel imaging receiver for high-speed indoor optical wireless communication system. Up to 12.5Gbps communication has been experimentally demonstrated and error-free beam footprint can be improved by >20%.
