Richard De La Rue obtained the PhD degree at University College London in 1972. He joined Glasgow University as Lecturer in late 1971 and retired from a full-time professorial position in September 2010. In 2011 he joined the Photonics Research Centre at the University of Malaya, for one year as Visiting Professor. In August 2012 he took up a position as Research Professor of Optoelectronics in the School of Engineering at the University of Glasgow - and completed his tenure in July 2014. He currently has the position of Honorary Professor in the School of Engineering at Glasgow University. He has Fellow status with the IEEE, OSA, the Royal Academy of Engineering, the Royal Society of Edinburgh, IET and EOS. He served as IEEE-LEOS Distinguished Lecturer for two years from mid-1999. Richard De La Rue’s research has been concerned with photonic crystal and photonic wire structures, waveguide microcavities, silicon photonics, metamaterials and graphene (oxide) photonics. Hiswork has also included research on compact semiconductor diode lasers, photonic-crystal LEDs and the applications of photonic crystal structures and metamaterial surfaces to bio-medical and organic material sensing. He has published more than 290 research and review articles - as papers in journals and magazines - and several book chapters.   Hans Peter Herzig received the Diploma degree in physics from the Swiss Federal Institute of Technology, Zurich, Switzerland, in 1978, and the Ph.D. degree in optics from the University of Neuchâtel, in 1987. From 1978 to 1982, he was a Scientist with the Department of Optics Development of Kern, Aarau, Switzerland, working in lens design and optical testing. In 1983, he was a Graduate Research Assistant with the Applied Optics Group, Institute of Microtechnology, University of Neuchâtel, Switzerland, working in the field of holographic optical elements. From 1989 to 2001, he was the Head of the Micro-Optics Research Group. From 2002 to 2008, he was a Full Professor and the Director of the Applied Optics Laboratory, University of Neuchâtel. He joined the faculty with the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, in 2009. Currently, he is a Professor with the EPFL. His research interests include refractive and diffractive micro-optics, nano-scale optics, and optical microsystems. Dr. Herzig is a member of the OSA, IEEE Photonics Society, EOS, and SSOM. 2009/2010 he was President of the European Optical Society (EOS). He served as the Conference Chairman for international conferences of EOS, IEE, IEEE/LEOS, OSA, and SPIE, and as a Guest Editor of four special issues of IEEE and OSA journals. He is the Editor of a well-known book on micro-optics (published in English and Chinese), author of 12 book chapters, over 130 journal papers and 250 conference proceedings.Since end of 2018 I’m Emeritus Professor at the EPFL. Martina Gerken receivedthe diploma degree in electrical engineering from the University of Karlsruhe, Germany, in 1998, and the Ph.D. degree in electrical engineering from Stanford University, Stanford, CA, USA in 2003. From 2003 to 2008 she headed the Micro- and Nanooptical Systems Group at the University of Karlsruhe, Germany. In 2008 she was appointed as a full Professor of electrical engineering and head of the Chair for Integrated Systems and Photonics at the Kiel University, Germany. Her research interest lies in the development of new sensor principles using microtechnology, nanotechnology and optical technology, as well as measurment system miniaturisation. Particular foci of her work are photonic crystals, organic optoelectronics as well as system simulations. She authored over 90 journal papers.
