Abstract
We are on the verge of a global revolution in lighting, as efficient and robust light emitting diode (LED) based 'solid state lighting' (SSL) progressively replaces traditional incandescent and even fluorescent lamps and finds its way into new areas including signage, illumination, signalling, consumer electronics, building infrastructure, displays, clothing, avionics, automotive, sub-marine applications, medical prosthetics and so on. This technology has tended to be viewed, so far, primarily as a way to improve energy- and spectral-efficiency, but what has been relatively little studied or appreciated is its profound implications for the future of communications.
We envisage the tremendous prospect of an entirely new form of high bandwidth communications infrastructure to complement, enhance and in some cases supercede existing systems. This LED-based technology will utilise the visible spectrum, largely unused for communications at present and more than 10,000 broader than the entire microwave spectrum. This promises to help address the 'looming spectral crisis' in RF wireless communications and to permit deployment in situations where RF is either not applicable (e.g. in underwater applications) or undesirable (e.g. aircraft, ships, hospital surgeries), but the implications are more fundamental even than that. The key point, in our view, is that lighting, display, communications and sensing functions can be combined, leading to new concepts of 'data through illumination' and 'data through displays'. Imagine, for example, a 'smart room', where 'universal illuminators' provide high-bandwidth communications, sensors monitoring the environment and people within it, provide positioning information and display functions, and monitor the quality of the light. Imagine novel forms of personal communications system that combine display functions and video with multiple, high-bandwidth communications channels. These could be through mobile personal communicators (developments of mobile phones or personal digital assistants) or even wearable and mechanically flexible displays.
Our ambitious programme seeks to explore this transformative view of communications in an imaginative and foresighted way. The vision is built on the unique capabilities of gallium nitride (GaN) optoelectronics to combine optical communications with lighting functions, and especially on the capability of the technology to implement new forms of spatial multiplexing, where individual elements in high-density arrays of LEDs provide independent communications channels, but can combine as displays. We envisage ultra-high data density - potentially Tb/s/mm2 - arrays of LEDs in compact and versatile forms, and will develop novel transceiver technology on this basis on both mechancially rigid and mechanically flexible substrates. We will explore the implications of this approach for multi-channel waveguide and free-space optical communications, establishing guidelines and fundamental assessments of performance which will be of long-term significance to this new form of communications.

Planned Impact
The UP-VLC programme proposes new types of intelligent and embedded communications infrastructure to address issues of great societal importance that also represent clear commercial opportunities (as our Letters of Support make clear). There is therefore considerable scope for Impact from the programme in terms of knowledge exchange with industry, and engagement with learned bodies, government and the general public on issues as diverse as energy efficient lighting and communciations, environmental management and monitoring, sustainability, widening access to 'the information society' and devolving personal communications.
Our interactions with industry will take place in three strands. The first is via the programme's Advisory and Monitoring Group (AMG) in which BAE Systems, Osram Opto Semiconductors, NEC, and Thorn Lighting, organisations with a strong commercial and operating base in the UK or Europe, will be involved. The second is via the wider group of committed project collaborators, including Compound Semiconductor Technologies, Bell Labs Ireland, ST Microelectronics, EV Group, Micro Resist Technology, and Avago, each of which have expressed interest in particular aspects of the programme which align with their business development plans. The third strand is industry more generally, with which we will engage via a concerted programme of Open Days, showcase events, general and trade-press briefings, trade shows etc. We will underpin our interactions with industry via professional handling of intellectual property (IP), including both 'know how' and patents, in which all investigators have string track records and many years' experience. The investigators also have considerable, direct experience in start-up company formation, and an important component of our Impact strategy will be to contionue to look for appropriate opportunities for the formation of such new enterprises.
A key factor in maximising benefit from our engagement with industry will be the University of Strathclyde's Technology and Innovation Centre. This £100 million initiative involves flexible and multi-disciplinary working with industry via new approaches and mechanisms, and co-location of industrial and academic research groups in a new and dedicated building. Prof. Dawson is the Academic Director of TIC with responsibility for Photonics, and he and several colleagues are planning the launch in 2012 of an Intelligent Lighting Centre (ILC) which will facilitate industrial engagement and knowledge exchange in solid state lighting and will provide a major interface and support to UP-VLC.

Description | This programme combined UK research strengths in nitrides, organic semiconductors, CMOS electronics and communications systems engineering to demonstrate new capabilities in communicating data via visible light - an area urgently required to complement existing WiFi. We have shown that multi-Gb/s visible light communications is possible using gallium nitride LEDs and explored novel multiplexing schemes with this technology for the first time. |
Exploitation Route | We set international benchmarks for performance of VLC devices and links and reported this widely at conferences, in the academic literature and at dedicated community meetings (e.g. Science for a Successful Nation). An example of the attention this has brought is over 670 citations to February 2011 (Google Scholar) for a paper we published on 3Gb/s performance from a gallium nitride LED. The findings are therefore widely disseminated for ourselves and others to build on. In early 2017, a 40-page invited review of the use of gallium nitride micro-pixel LEDs was published in Semiconductor Science and Technology. During 2020, the original Co-I Prof Haas also joined Strathclyde, which will clearly facilitate future joint work with the Strathclyde team. |

Description | This programme formed the focus for UK research in visible light communications. Organisations including BAE Systems and OSRAM were kept abreast of the progress via their membership of the project's advisory board. This led to broader industrial engagement including direct contract work with companies including Thales, plus Phase 1 Quantum Technology Hub partnership projects with Aralia Systems and Clyde Space. Our programme has come to wide attention through e.g. EPSRC Science for a Successful Nation and Connected Nation events. In May 2016 we held an extremely successful Open Day in London, with Nobellist Prof Amano as a closing speaker. The project has generated prestigious invitations for overview articles from the original team, including a 2017 Semiconductor Science and Technology review, and a 2020 Philosophical Transactions article. |

Title | High speed visible-light communication using organic light-emitting diodes based on fluorescent and phosphorescent emitters (dataset) |
Description | Visible light communications (VLCs) using organic light-emitting diodes (OLEDs) are a promising technology because of unique features of OLEDs such as arbitrary sizes and shapes, and providing a glare-free illumination. However, the reported best data transmission rate of OLEDs in VLC, so far, are quite low (~50 Mbps), even in unpractical short data link (12.5 cm). To enhance the data rate, high signal-to-noise-ratio and high modulation bandwidth is required. Here, we report a systematic investigation of OLEDs, in particular, the influence of light emitting materials and device size. Because both points are related on both signal-to-noise-ratio and the bandwidth, and they have fundamental trade-off in data rate, the understanding of the influence on the data rate will be basics to improve furthermore the date rate. However, in the early stage of development of OLEDs for VLCs, their influence were not investigated. Through the investigation, we found that a conventional fluorescent emitter, 2,5,8,11-tetra-tert-butylperylene, with the smallest device area of 1.2 × 10-3 cm2 are important to achieve higher data transmission rate. That means that the enhancement of data rate by increasing the bandwidth is much effective than the enhancement of the data rate by increasing radiance. Through these investigation, we achieved a record data transmission rate of 663 Mbps with an implementation of orthogonal frequency-division multiplexing, which is the 13 fold improvement of the data rate from the best data rate reported so far even in more practical 2 m data link. |

Title | RECEIVER ASSEMBLY, DATA COMMUNICATIONS SYSTEM, AND DATA COMMUNICATIONS METHOD |
Description | A receiver assembly (100) and data communications method are disclosed. In one arrangement, a receiver assembly (100) comprises a concentration stage (14). The concentration stage (14) receives radiation via an input surface (120) and outputs concentrated radiation via an output surface (122). The concentration stage comprises a wavelength converting member (6) that converts radiation to longer wavelength radiation. An optical element (102) is provided which is such that if a plane wave of radiation is incident on the optical element a spatial distribution of radiation derived from the plane wave on the input surface of the concentration stage varies as a function of a direction of incidence of the plane wave relative to the optical element. A plurality of detectors (42) are provided, each detecting radiation output from a different portion of the output surface of the concentration stage. |
