Journal ArticleDOI
A 3-Gb/s Single-LED OFDM-Based Wireless VLC Link Using a Gallium Nitride $\mu{\rm LED}$
Dobroslav Tsonev,Hyunchae Chun,Sujan Rajbhandari,Jonathan J. D. McKendry,Stefan Videv,Erdan Gu,Mohsin Haji,Scott Watson,Anthony Kelly,Grahame Faulkner,Martin D. Dawson,Harald Haas,Dominic O'Brien +12 more
TL;DR: In this article, the authors presented a visible light communication (VLC) system based on a single 50-μm gallium nitride light emitting diode (LED) with a 3-dB modulation bandwidth of at least 60 MHz.
Journal ArticleDOI
High Bandwidth GaN-Based Micro-LEDs for Multi-Gb/s Visible Light Communications
Ricardo Ferreira,Enyuan Xie,Jonathan J. D. McKendry,Sujan Rajbhandari,Hyunchae Chun,Grahame Faulkner,Scott Watson,Anthony Kelly,Erdan Gu,Richard V. Penty,Ian H. White,Dominic O'Brien,Martin D. Dawson +12 more
TL;DR: In this paper, the authors report on progress in the development of micro-scale GaN LEDs (micro-LEDs), optimized for visible light communications (VLC) using ON-OFF-keying, pulse-amplitude modulation and orthogonal frequency division multiplexing modulation schemes.
Journal ArticleDOI
LED Based Wavelength Division Multiplexed 10 Gb/s Visible Light Communications
Hyunchae Chun,Sujan Rajbhandari,Grahame Faulkner,Dobroslav Tsonev,Enyuan Xie,Jonathan J. D. McKendry,Erdan Gu,Martin D. Dawson,Dominic O'Brien,Harald Haas +9 more
TL;DR: A trichromatic approach to wavelength division multiplexing using the different colours required to generate white light to transmit different data streams is described and the influence of colour combination on achievable data rate is analysed.
Journal ArticleDOI
A review of gallium nitride LEDs for multi-gigabit-per-second visible light data communications
Sujan Rajbhandari,Sujan Rajbhandari,Jonathan J. D. McKendry,Johannes Herrnsdorf,Hyunchae Chun,Grahame Faulkner,Harald Haas,Ian Watson,Dominic O'Brien,Martin D. Dawson +9 more
TL;DR: The state-of-the-art technology enabling bandwidth of GaN LEDs in the range of >400 MHz is explored and advances in key technologies, including advanced modulation, equalisation, and multiplexing that have enabled free-space VLC data rates beyond 10 Gb/s are outlined.
Journal ArticleDOI
High-Speed Integrated Visible Light Communication System: Device Constraints and Design Considerations
Sujan Rajbhandari,Hyunchae Chun,Grahame Faulkner,Katherine Cameron,Aravind V. N. Jalajakumari,Robert Henderson,Dobroslav Tsonev,Muhammad Ijaz,Zhe Chen,Harald Haas,Enyuan Xie,Jonathan J. D. McKendry,Johannes Herrnsdorf,Erdan Gu,Martin D. Dawson,Dominic O'Brien +15 more
TL;DR: The design and fabrication of integrated transmitter and receiver components are reported and a preliminary result of a MIMO system implementation operating at a data rate of 1 Gbps is demonstrated.
