John Lincoln
Organisation: Photonics Leadership Group and Harlin Ltd
Role: Chief executive
For John Lincoln, there is only one game in town in terms of photonics research – delivering the transition to a net zero economy. ‘While energy efficiency will be a focus for
the near future, photonics has the capacity to impact across the board, from enabling the circular economy through verification of materials through to increasing energy generation efficiency in renewables or reducing energy consumption in the data economy,’ he said. However, he believes that charting a course through the chaos of UK politics
‘to generate win-win growth scenarios’ for industry and innovators will be challenging. ‘We are currently standing up a new
Future Photonics Leaders group, cognisant that while the timescales for impact from quantum computing to net zero reach far into the future, those who will be leading the photonics innovation system of that future should be fully engaged in shaping it today.’ You can find Lincoln online at

Callum Littlejohns
Organisation: University of Southampton Role: Cornerstone Coordinator
Callum Littlejohns leads a silicon photonics rapid prototyping service called Cornerstone, which allows him to interact with research labs and companies operating in multiple disciplines. ‘Silicon photonics markets are rapidly expanding with new application areas that cover consumer markets such as sensing for smart watches and lidar for driverless cars,’ he said.
‘Silicon photonics already supports the
reduction of the carbon footprint of the internet and will soon underpin healthcare and mobility. And let’s not forget quantum. It is likely that the first useful quantum
Elena Lopez
Organisation: Fraunhofer Institute for Material and Beam Technology (IWS)
Elena López heads a team developing laser and printing technologies for procedures involved in the fabrication of individualised components and functional structures made of metals, semi-conductors and polymers. López finished her PhD thesis, on plasma- chemical etching of silicon solar wafers, at the Dresden University of Technology. Since 2014, she has focused her work on additive manufacturing technologies. Fraunhofer IWS recently joined
forces with researchers from Hamburg and Melbourne working on combining ultrasound with laser deposition welding

to 3D print more robust, more durable and cheaper components for aerospace, toolmaking and other industries. The technology, known as UltraGrain, ‘can improve properties such as fatigue resistance, strength, resilience and ductility and significantly reduce the susceptibility to cracking of additively manufactured components’, said López. She is also the general manager of
Agent-3D, an additive manufacturing consortium of research institutions and industrial members including Audi, Airbus and Bombardier.

computer will rely on silicon photonics technologies,’ he said. ‘The biggest challenge is developing the
next generation of researchers, engineers and technicians to enable silicon photonics technologies to thrive and grow. Staff in our field are already in high demand and that is only going to grow, so it is up to us all to inspire young people to enter into the field of photonics.’ You can find Littlejohns online at linkedin. com/in/callum-littlejohns-14419813b/. He is co-chairing a silicon photonics symposium at SPIE Photonex on 6-8 December in Birmingham, UK.
