Photonics research programmes to revolutionise healthcare technology Light is used in a multitude of ways to identify molecules, detect disease and manipulate chemical and cellular processes. Novel low-cost light sources, advanced detection schemes, new materials and nanotechnologies are now enabling further rapid growth in the application of light to chemistry and medicine. Here we describe new ORC directions in devices and techniques for DNA analysis, point-of-care diagnostic systems, mid-infrared and pulsed light sources and integrated photonic devices which will advance our understanding of biochemical processes and generate advanced optical healthcare technologies.

Grants for new devices for healthcare and industry

New grant for photonic technologies

New applications in healthcare and telecommunications will be made possible by two grants awarded to the Optoelectronics Research Centre (ORC) by the Engineering and Physical Sciences Research Council (EPSRC).

A grant awarded to the ORC will provide a platform for the development of the next generation of cheaper, faster and greener devices.

A grant for £0.5 million awarded to a team led by Dr Anna Peacock, will combine two important and highly topical optical technologies: optical fibre tapers and semiconductor functionalised fibres. This research will lead to the development of optoelectronic devices spanning a wide range of wavelengths with the potential to impact many disciplines.

The ORC has just been awarded a £1.4 million platform grant by the Engineering and Physical Sciences Research Council (EPSRC) in the area of integrated photonics which will lead to the development of new devices including new kW-class lasers, compact on-chip amplifiers and biosensor arrays for infectious diseases. High-power lasers, the size of a fingernail for machining and laserprocessing applications, pollution sensors to monitor climate change, early threat detection security devices and fast universally accessible disease screening, will all be made possible throughout the four-year period of the grant.

“The award of this grant is very exciting as this research will be crucial for the development of our semiconductor fibre technology and its potential applications,” said Dr Peacock. “The construction of commercially relevant devices such as ultra-compact broadband, The investigating team are Professor Rob Eason, Principal mid-infrared sources for healthcare, frequency comb generators for Investigator, with co-investigators Professors James Wilkinson, Dave spectroscopy and sensing, and highly nonlinear optical couplers and Shepherd, Peter Smith and Dr Jacob Mackenzie, who are working with switches for ultrafast telecoms applications should stimulate a fruitful seven external partner organisations and each responsible for specific collaboration with industry.” areas of interest.

Student success Celebrating the achievements of ORC students

ions 10 success ORC graduate IONS 10, the tenth international conference organised by the International OSA (Optical Society) Network of Students, saw young scientists from around the world descend upon the University of Southampton. The three-day event, held in August at the Optoelectronics Research Centre, is the latest in the series organised by students for students working in all areas of optics and photonics. It provides a platform for early-career researchers to present their fields and encourages global networking. More than 80 delegates, who came from as far away as Mexico, India and Israel, were able to view the University’s world-class photonics facilities. As well as presenting their own research, they heard plenary talks from eminent photonics community speakers including Dr Emma Springate of the Central Laser Facility and OSA President Professor Chris Dainty.

awarded thesis prize by IOP The Institute of Physics (IOP) has awarded ORC graduate, Dr Eric Plum, their Quantum Electronics and Photonics PhD Thesis Prize for his Thesis entitled “Chirality and metamaterials.” This is the second year running that the £250 prize has been awarded to an ORC graduate, after it was awarded to Dr Nikitas Papasimakis last year. Prior to receiving this prize Eric’s thesis had been widely publicised through 47 publications including three Physical Review Letters, a book chapter and 18 conference papers linked to invited and keynote talks. The prize recognises Eric’s theoretical description and experimental realisation of novel metamaterials with optical activity, asymmetric transmission and negative refractive index, which have already attracted hundreds of citations. On receiving the prize Eric commented “I am honoured to receive the thesis award from the Institute of Physics and I would like to take the opportunity to thank Professor Nikolay Zheludev and Dr Vassili Fedotov for their guidance during my PhD.”Eric has recently been appointed as a Leverhulme Advanced Research Fellow associated with the EPSRC Centre for Photonic Metamaterials.

ORC student wins Marconi Young Scholar award A talented engineering researcher from the Optoelectronics Research Centre, has been honoured at the prestigious Marconi Society Awards in San Diego, California. PhD student Joseph Kakande, from Uganda, was selected as one of only three Marconi Young Scholars in this fourth year of the awards for his cutting-edge work in making communications even faster by using all-optical fibres. Marconi Society Chairman Emeritus Robert Lucky said that the scholars selection committee “looked for candidates who showed the potential to win the Marconi Prize – the equivalent of the Nobel Prize in communications science – at some point in the future. As a point of reference, Marconi Fellows have been at the forefront of every modern advance in telecommunications and the Internet.”

Joseph is congratulated by Robert Tach at the Marconi Society Awards

Joseph’s work focused on all-optical signal processing as the means of meeting the growth in demand for high-capacity optical communications. The current system of optical-to-electrical-tooptical conversion creates speed and power bottlenecks that cannot sustain the exponential growth in communications. “Electronics is really great for processing,” Joseph explains, “but it can only work so fast.” Newer technology aims to replicate the functionality of electronic transistors, but uses optical components – flexible pure glass fibres roughly the size of a human hair that are capable of transferring information from one end to the other over longer distances. The advantage is speed: optical techniques easily process more than 10 billion bits a second – about 10 times faster than the fastest conventional computer. Joseph’s research aims to develop novel methods for processing high spectral efficiency phase-encoded optical signals at ultra-high baud rates, using nonlinear fibre optic technologies. In essence, that means using light to control optical signals on ultra-fast time scales. His research is already published in several top journals including the Nature group, and has led to three patent filings, with more in the pipeline.

Joseph would like to work for a large corporation in its research and development department. He says: “As a child, I had a fascination with electronics and I always wanted to work at Intel.” Named Best Student at National Level in Uganda, where he was a student at St Mary’s College Kisubi, Joseph attained first-class honours in electronic engineering from the University of Hull, and is shortly to receive his PhD in optoelectronic engineering from the University of Southampton. His particular interest is in exploring how optical communications, which have revolutionised technology in the developed world, can be deployed in the Third World to empower its most deprived people. As his University co-supervisor, Optoelectronics Research Centre Deputy Director David Richardson says, “I think Joseph has all the capabilities to become a real research superstar.”

Student success Celebrating the achievements of ORC students

Grand Prize for ORC student ORC student, Eric Numkan Fokoua, has won the coveted grand prize of the 2012 Corning Outstanding Student Paper competition at this year’s OFC Conference in Los Angeles. The award recognises student leaders in the field of optical communications: finalists are judged on innovation, research excellence and presentation skills. Selected from 362 submissions, Eric’s paper relates his research on Spatial Division Multiplexing (SDM) in hollow-core photonic bandgap fibres. He explains: “In recent years, SDM has emerged as one potential solution to the predicted capacity crunch in current telecom systems. By implementing SDM in hollow-core photonic bandgap fibres, we exploit the benefits of low optical nonlinearity and potential low loss that result from light propagation in a hollowcore. One of the first steps is to fully understand the properties of these fibres and in particular the mechanisms responsible for loss. At the conference, we presented a method that accurately describes light scattering at the many air-glass surfaces within the fibre. “The Corning student paper competition at the OFC is a big deal for students working in Optical Communications and it was simply amazing to win. I am grateful to my supervisors Dr Francesco Poletti and Professor David Richardson for their support and guidance, as well as our marvellous fabrication team.”

CLEO 2012 paper success ORC students are making the grade at CLEO this year: they’ve had a 100 per cent success rate for their submissions to one of the Photonics Industry’s premier events. All 36 of the papers submitted have been accepted for presentation. Professor Michalis Zervas said: “This is a great achievement given that this year there were 176 submissions to Category 11 alone (the highest number among all the categories) and the success rate was about 40 per cent. It was a really tough competition.” Congratulations to you all, especially Ee Leong Lim, whose paper got the highest score among the ORC submissions.

Bridging the gap between glass and silicon The University of Southampton’s Optoelectronics Research Centre (ORC), in collaboration with the Universities of Surrey and Cambridge, is pioneering research that will develop functionality of new materials such as amorphous chalcogenides.


Light Times | issue 1 2012

These materials bridge the gap between glasses, such as those that form our optical fibre networks, and semiconductors, such as the silicon chip. Chalcogenides are already in use for thin-film and fibre waveguides, switching, light emission and amplification while electronic applications, such as phasechange memory, are leading the way in microelectronics. Microelectronics is a vast market; worldwide production was €873 billion in 2010, with European volume growing 23% that year. The gadget economy is becoming a bigger and bigger part of the business world, and may be one of its more important growth engines. The materials being developed in this project are already forming the basis for a new generation of electronics.

amplifiers, switches, logic gates and memory cells will be of great interest to large electronics companies.” The ORC has long established links with leading international companies including BAE Systems, Qinetiq, Ilika Technologies plc, Gooch & Housego and IBM. Industrial interest is further reinforced by the involvement of a leading international expert in the field of applications of ion implantation, Dr Jonathan England, who is Senior Technologist at Varian Semiconductor Equipment Associates (VSEA), a subsidiary of Applied Materials. Jonathan is undertaking the role of project mentor, with VSEA sponsoring his time to the project.

Dr Richard Curry, University of Surrey project leader, explains: “Our work will impact Professor Dan Hewak, project leader from the on policy makers, stakeholders, research ORC, says: “We expect this project to generate councils and government - providing clear measurable results that demonstrate the considerable attention in both research and value of investment in UK-led research. industrial communities.

Professor Stephen Elliott, University of Cambridge project leader, adds: “This combined computational and experimental project holds out the promise of delivering new functional materials, with a wide range of applications of interest to industry, and which should provide opto-electronic technologies beyond silicon.” The £1.48 million Engineering and Physical Sciences Research Council (EPSRC)- funded project forms an important component of the EPSRC’s Grand Challenge in Microelectronics entitled, ‘Performance Driven Design for Next Generation Chip Design’. The grant is initially awarded over two years during which the number and range of collaborations and industrial interest is expected to grow in the new chalcogenidebased optoelectronic platform.

A lasting memory

UKIERI skills development programme A team of top researchers from the ORC, led by Professor David Payne, visited Kochi in December to participate in the UK-India Education Research Initiative final meeting. David, as well as chairing session one of the conference, gave a pre-dinner speech on the first evening.

HRH, Duke of York and Professor David Payne discuss growing the UK’s technology market.

His Royal Highness, the Duke of York, was presented with the so-called ‘Superman memory crystal’ from Professor David Payne, ORC Director, during his recent tour of the ORC. The nanostructured fused quartz medallion, was imprinted by a femtosecond laser with an image of the Duke. The technology enables vast quantities of five-dimensional data to be stored indefinitely. To accompany the gift, a laser-etched plaque was also presented, courtesy of ORC spin out company, SPI. “The Duke was fascinated by our start-up record and mused on the merits of inward investment versus organic growth to create the major British companies of the future. He noted the success of SPI in particular, having met them at the careers fair,” said David. Commenting on the visit, the Duke said: “I came to the university to see what they are doing and to understand the world-class research that is going on here, especially in optoelectronics in which it is a global leader.” Find out more about nanostructured glass, the technology behind the gift on page 18.

The UKIERI team celebrate the successes of phase one of the programme

“At this event we’ve presented findings from our major collaborative project: ‘Application-Specific Microstructured Optical Fibres’ (MOFs). This fascinating variant of optical fibres, enables easy manipulation of light propagation, opening up new applications in telecommunications and beyond.” commented David. MOFs offer high nonlinearity or extremely low nonlinearity capabilities: high nonlinearity capability enables the generation of broadband and coherent supercontinuum light for applications in optical coherence tomography (OCT) used in medical diagnosis, or for use as frequency combs. Strongly wavelength sensitive, MOFs offer a new platform for design and realisation of a wealth of allfibre exotic devices. “The ORC is proud to be involved in the UKIERI programme, underpinning successful partnering and mentoring relationships between the UK and Indian ministries, institutions and sectoral experts,” David added. The UKIERI programme started in 2006 with the aim of developing opportunities for UK-India collaboration across academic research, schools and further education colleges. Among the successes of the first five years, UKIERI has: – i nvested in 182 UK-India partnerships – s upported 55 PhD scholarships and fellowships and 88 facilitation grants – g iven 393 British students the opportunity to visit and study in India – f acilitated work placements to 106 Indian graduates Find out more at:

Faster lasers to map jet engines The Optoelectronics Research Centre is developing lasers that will improve scientists’ understanding of the combustion process in jet engines and reduce emissions. The ORC is working on the £2.7 million research project called FLITES (Fibre-Laser Imaging of gas Turbine Exhaust Species). It is funded by the Engineering and Physical Sciences Research Council, led by University of Manchester and aims to develop technology to reduce jet engine emissions. “FLITES will allow us to map different chemical species and soot in the exhaust plume of aero engines,” said Professor Johan Nilsson at the ORC. “This will create a better understanding of the combustion process in the engine and enable us to optimise it at lower cost - with the increasing interest for substitution of fossil fuels with bio-fuels in the aviation industry, this is particularly important. Currently the cost is too high and the data collected too limited for extensive evaluations of new biofuels in aero-engines.” FLITES aims to establish a world-leading capability to map several exhaust species from aeroplanes using tomographic imaging. The ORC, the University of Manchester, the University of Strathclyde, and commercial partners including Rolls-Royce, Shell, Covesion, Fianium and OptoSci, will work on the fouryear study, motivated by lower-cost engine evaluation and monitoring and reduced carbon dioxide emissions and pollution. It is expected that the research project will enhance turbinerelated research and development capacity in both academia and industry by opening up access to exhaust plume chemistry. It will underpin a new phase of low-net-carbon development that is underway in aviation, based on bio-derived fuels, and which entails extensive research in turbine engineering, turbine combustion, and fuel product formulation.

A striking image produced by ORC researcher, Martynas Beresna has won third prize in the OSA’s 2011 After Image Photographic competition. The unexpected, beautiful diffraction pattern produced from a femtosecond laserwritten structure caught the judges attention.

Nanostructured glass. New imaging and recording technology Researchers at the Optoelectronics Research Centre have developed new nanostructured glass optical elements, which have applications in optical manipulation and will significantly reduce the cost of medical imaging. In a paper entitled Radially polarized optical vortex converter created by femtosecond laser nanostructuring of glass, published in Applied Physics Letters, a team led by Professor Peter Kazansky at the University of Southampton’s ORC, describe how they have used nano-structures to develop new monolithic glass space-variant polarization converters. These millimetre-sized devices generate whirlpools of light that enable precise laser material processing, optical manipulation of atom-sized objects, ultrahigh resolution imaging and potentially, table-top particle accelerators. In a recent breakthrough, the research team found that the technology can be developed further for optical recording; at sufficient intensities, ultrashort laser pulses can be used to imprint tiny dots (like 3D pixels) called voxels in glass. Their previous research showed that lasers with fixed polarization produce voxels consisting of a periodic arrangement of ultra-thin (tens of nanometers) planes. By passing polarized light through such a voxel imprinted in silica glass, the researchers observed that it travels differently depending on

the polarisation orientation of the light. This form birefringence phenomenon is the basis of their new polarisation converter. The advantage of this approach over existing methods for microscopy is that it is 20 times cheaper and it is compact. “Before this we had to use a spatial light modulator based on liquid crystal which cost about £20,000” said Professor Peter Kazansky. “Instead we have just put a tiny device into the optical beam and we get the same result.” Since publication of the paper in 2011, the researchers have developed this technology further and adapted it for a five dimensional optical recording. Traditional CDs and DVDs store data on their surface in two dimensions, and holographic discs can store it in three. “We have improved the quality and fabrication time and we have developed this five dimensional memory which means that data can be stored on the glass and potentially last forever,” said Martynas Beresna, lead researcher for the project. “No one has ever done this before.” The researchers are working with the Lithuanian company Altechna to introduce this technology to the market. This work was done in the framework of EU project Femtoprint.

Crystalline materials enable high speed electronic function in optical fibres Scientists at the University of Southampton, in collaboration with Penn State University have, for the first time, embedded the high level of performance normally associated with chip-based semiconductors into an optical fibre, creating high speed optoelectronic function.

A gigahertz bandwidth semiconductor photodetector is integrated directly inside a microstructured optical fibre, adjacent to its light guiding core. Finite element analysis in this image shows how this semiconductor device couples seamlessly with data pulses in the glass optical fibre.

The potential applications of such optical fibres include improved telecommunications and other hybrid optical/electronic technologies. This transatlantic team will publish its findings in the journal Nature Photonics.

is a challenge. Another challenge is the alignment of pieces that are so small. An optical fibre is the width of a human hair. On top of that, there are light-guiding pathways that are built onto chips that are even smaller than the fibres by as much as 1000 times, so imagine just trying to line those two devices up. That feat is a big challenge for today’s technology.”

The team has taken a novel approach to the problems traditionally associated with embedding this technology. Rather than merge a flat chip with Dr Anna Peacock, who holds a Royal Academy a round optical fibre, they found a way to build a of Engineering Research Fellowship, added: new kind of optical fibre with its own integrated electronic component, thereby bypassing the need “The incorporation of optoelectronic device to integrate fibre-optics onto a chip.
