Long-wavelength VCSELs: Materials, Devices and Applications
Prof Markus-Christian Amann, Technische Universität München
InP-based VCSELs based on the buried-tunnel-junction (BTJ) technology for the 1.3-2.5 μm wavelength range are presented. These devices show excellent lasing behaviour regarding stationary and dynamic characteristics such as very small threshold currents and threshold voltages around 1 mA and below 1 V, respectively. At 85°C, output powers in the milliwatt range are observed. Nanofabrication techniques are applied to accomplish lasing with deterministic and stable polarisation as well as emission into an equally spaced 4-wavelength grid. Accordingly, stable spectral single-mode emission with side-mode suppression ratio well beyond 40 dB is maintained over the relevant temperature and current ranges. The lasers accomplish high-speed and energy-efficient modulation exceeding 20 GHz in small-signal and 30 Gb/s in NRZ pulse modulation. They can be made tuneable with continuous tuning over more than 50 nm. The wavelength range further up to 3μm, which is important for gas-sensing applications, is addressable by GaSb-based BTJ-VCSELs. Recent device results and gas sensing application examples are demonstrated.

Theme 2: Quantum Sciences
Dr Thierry Ferrus, Hitachi Cambridge Laboratory
Superconductivity in graphene: new physics and applications
Dr Jonathan Prance, Lancaster University
Although graphene is not a superconducting material, super-current is able to flow several microns through high-quality graphene when it is placed in close proximity with a superconductor. The unusual properties of graphene mean that this superconducting proximity effect can now be observed in a material where the density of carriers can be controlled and where carrier transport is ballistic and coherent. In this talk I will present measurements of high-quality, niobium-graphene-niobium junctions and describe some of the unexpected behaviour seen in this system. In particular, we have found that super-current through the junctions, which should be supressed in magnetic fields of a few millitesla, actually survives in magnetic fields as high as 1 T. We attribute this high-field supercurrent to mesoscopic states that exist near the edges of the graphene. The work reveals new regimes where super-current can be controlled by quantum confinement and cyclotron motion, and points the way to new applications for graphene-based superconducting devices.
Jonathan Prance is a Lecturer in the Physics Department at Lancaster University. He studies the low-temperature properties of nanoelectronic structures and their applications to Quantum Technologies.

Nano-Identification: The Fingerprints of the Future
Jonathan Roberts, Lancaster University
The rise of modern technology has ushered in exciting new technologies such as self-driving cars, wearable technology and the ability to make purchases with a touch of your phone. This upsurge of technology has, unfortunately, provided a pathway in which criminals can tread; using these advanced tools for nefarious purposes. A popular example is counterfeiting, which leads us to a question: How do you tell the difference between a real device and a fake device? The answer to this question lies in the production of devices that provide a check of authenticity - much in the same way that a person’s fingerprint can be used to verify their identity. Contemporary anti-counterfeiting solutions are used for this purpose but have multiple flaws, the most critical of which is the readiness with which they can be duplicated, providing criminals with a way to bypass the security. Here at Lancaster, we are creating devices using quantum technologies that can provide this check of authenticity with infallible security. To do this, we have manufactured nanoscale devices that comprise random imperfections from device-to-device on the atomic level. In this talk I will describe how by using unique and unclonable imperfections on this scale, we have generated an impassable barrier for criminals and counterfeiters, leading to a safe and secure future for everyone.
Jonathan started his PhD in 2012 with the EPSRC NowNano doctoral training centre, a multidisciplinary collaboration between Lancaster University and The University of Manchester, after achieving first class honours in a Masters in Physics from the University of Sheffield. His research interests include nanotechnology, optoelectronics and semiconductor devices with a speciality in their applications to security. In 2015, he was the overall winner of the EPSRC UK ICT Pioneers award, a prestigious competition held for ICT-related disciplines with judges from Samsung, Facebook, EPSRC, HP, BT, dtsl and dstl. He also won the IOP research communication award at the UK semiconductors conference and has published a first-author paper into the Nature journal Scientific Reports which was subsequently highlighted on the BBC news website.

Theme 3: Artificial Materials
Unlocking the Potential of Metal-Glass Composites
Dr Svetlana Zolotovskaya, Lancaster University
Glass staining with noble metal particles has a long history. The earliest known and most famous example of such a glass is the ‘Lycurgus’ cup — the Roman goblet dated from the 4th century AD. It appears red in the transmitted light and green when viewed in the reflected light. Its unique appearance is determined by the presence of metal particles with dimensions substantially smaller than the wavelength of light.
In her presentation, Svetlana will focus on the artificial materials created by controllable formation of metal nanoparticles in glass matrices, so-called Metal-Glass Composites. She will explore pathways to tailor their optical properties in order to provide new functionalities for a wide range of applications from security and sensing to optical component integration.
Svetlana joined Lancaster University in September 2015, as a Lecturer in Materials Science & Engineering – part of the 50th Anniversary Lectureships Scheme. Her current research interests include development of photonic materials & devices, biomedical photonics, laser spectroscopy and laser micro/nano materials processing. Svetlana obtained her PhD in 2009 on the development of novel photonics systems for biomedical applications at the University of Dundee and worked as a postdoctoral fellow at the University of Dundee, University of St Andrews and STFC Daresbury Laboratory between 2009 and 2015.
SYMETA: SYnthesizing 3D METAmaterials for RF, microwave and THz applications
Prof. Yiannis Vardaxoglou, Loughborough University
SYMETA is a 5 year research programme and a 5 University consortium supported by 15 companies addressing EPSRC’s Grand Challenge: Engineering across length scales, from atoms to applications; SYMETA is a radical research project with the potential to transform communication, electronics and manufacturing industries. Metamaterials offer a unique opportunity, however up until now, manufacture of metamaterials has been limited to the small-scale through work taking place in University labs and workshops. SYMETA offers a truly disruptive advancement in the technology: to scale up the manufacture of materials with end-user-defined electromagnetic parameters, with metallic, dielectric and magnetic inclusions. Wireless products will be manufactured at rapid rates, at the point of use and with minimal waste. SYMETA will manufacture materials from which the subwavelength building blocks ("meta-atoms") can be constructed. SYMETA will electromagnetically characterise current materials used in additive manufacture and will design, manufacture and test new materials developed by the consortium partners.
The talk will introduce this Grand Challenge and outline SYMETA’s building blocks and organisation.

Modelling Porous Organic Materials for Energy Applications – a bottom-up approach to rational property design
Dr Abbie Trewin, Lancaster University
Materials with molecular-scale porosity are important in wide range of energy applications such as gas storage, molecular separation, heterogeneous catalysis, energy generation and energy storage.
The ability to rationally predict and hence design the porous properties of materials for specific energy applications is a key challenge for materials discovery. Here, I show how taking a bottom-up approach and assessing the structure-directing influences of the material building blocks can lead to new ‘rational design’ strategies.
