Prof Sir David Payne, University of Southampton, UK

Prof D. N. Payne is an internationally distinguished research pioneer in photonics, having been in the field for over 50 years. Optical fibre technology is one of the greatest scientific successes of the last three decades and Payne’s contributions are acknowledged as seminal in many areas.  Optical fibres underpin the internet, provide new laser capability and environmental sensing, and drive growth to the benefit of all nations. Payne’s work spans many diverse areas of photonics, from telecommunications and optical sensors to nanophotonics and optical materials. With his colleagues he has made many of the key technical achievements in almost every area of optical fibre technologies and his work has had a direct impact on worldwide telecommunications, as well as nearly all fields of optical R&D. As a result, he is the most highly honoured UK scientist in photonics. Payne’s pioneering work in fibre fabrication in the 70’s resulted in almost all the special fibres in use today.  He led the team that in 1985 first announced the silica fibre laser and the Erbium-Doped Optical Amplifier (EDFA), the device that fuelled an explosive growth in the internet through its ability to transmit and amplify vast amounts of data.  The EDFA is widely regarded as being one of the foremost and most significant developments in modern telecommunications.

Analog programmable photonic computing: A new paradigm for data processing, José Capmany, iPRONICS Programmable Photonics S.L., Spain.

To date, the primary efforts in optical computing have concentrated on adapting well-established paradigms from other fields, such as digital electronics and neural networks, to photonic technologies. However, photonics is fundamentally a linear technology and lacks a specialized computing framework to fully harness its capabilities. Analog programmable photonic computing (APC) represents an initial step in this direction. This talk will explore some of the fundamental principles and technologies of APC.

Enabling a World of Secure Computing through the power of Photonics, Nick New, Optalysys Ltd., UK. Recent surges in demand for ever greater data movement and processing needed to train and utilise large AI models has seen a surge in interest and momentum in photonics - and in particular silicon photonics based approaches. Significant investment has led to breakthrough advances in optical interconnects and transport layers within chip architectures. However, by incorporating the natural processing effects of coherent interference, Optalysys is going further, by bringing transport and compute together in the same silicon plane. The approach provides for a new chip architecture that may be applied to processes dominated by transform functions - in particular in the nascent field of Secure Computing. Dr New will present how the technology is being applied to solving a huge computational challenge in accelerating Fully Homomorphic Encryption methods - which allows data to be processed by multiple parties without ever being exposed. In doing so the development has the potential to define how we use our data on the internet in the future and to become part of the fabric of cloud computing.

Twisted light in chiral photonic crystal fibres, Philip St.J. Russell, Max Planck Institute for the Science of Light, Germany. Two-dimensional photonic crystals that are extended and chirally twisted in the third dimension provide novel opportunities for controlling light, but are very difficult to realize using conventional planar techniques. In contrast, low-loss chiral structures are straightforward to produce by drawing photonic crystal fibre (PCF) from a spinning preform. This has led to a series of novel experiments uncovering interesting and useful properties, for example, twisted PCF supports helical Bloch modes that are circularly and topologically birefringent, offering robust preservation of polarization state and topological charge, and permitting enhanced control of nonlinear optical effects such as supercontinuum generation, Raman and Brillouin scattering. Recent work reveals in addition that light can be exponentially localised in chiral arrays of coupled waveguides, as seen experimentally in twisted coreless PCF.
