Professor Charlie Ironside has over 30 years’ experience in semiconductor optoelectronics research and in particular microfabrication of semiconductor photonic components such as laser diodes for optical communications systems, optical sensing and optical metrology systems. He has published over 120 research journal publications and 200 conference papers and has won awards for transferring research knowledge for commercial exploitation. Bruno Romeira is a staff researcher at the International Iberian Nanotechnology Laboratory, Portugal. He received a PhD degree (summa cum laude) in physics and the European PhD degree from the University of Algarve, Faro, Portugal, jointly with the University of Glasgow, UK, and the University of Seville, Spain, in 2012. His research cuts across several disciplines in applied physics and engineering, which include semiconductor physics, quantum nanoelectronics, low-dimensional nanostructures, nanophotonics and neuromorphic devices. José Figueiredo is an associate professor at the Faculty of Sciences of the University of Lisbon, Portugal. He holds a BSc in physics (optics and electronics), a MSc in optoelectronics and lasers, and a PhD in physics (microelectronics and optoelectronics, in a joint programme with the University of Glasgow, Scotland) from the University of Porto, Portugal. His research interests in the fields of applied physics and physics engineering include quantum electronics, photonics, semiconductor physics, and semiconductor photonic components.
