Stavros Pissadakis - OSA Senior Member Stavros Pissadakis - OSA Senior Member

Dr. Stavros Pissadakis is a Director of Research at FORTH-IESL, leading the Photonic Materials and Devices Laboratory (PMDL). He obtained his Ptichion degree in Physics from the University of Crete, Greece and his Ph.D. degree in Electrical Engineering/Photonics from the Optoelectronics Research Centre (ORC), University of Southampton, UK. He has been employed as a Research Fellow in ORC, UK, as Visiting Lecturer in the Department of Computer and Electronic Engineering, Technical University of Crete, Greece, as Visiting Assistant Professor in Physics Department, University of Crete, and as Visiting Professor at the Information Engineering Department, University of Parma, Italy. He joined FORTH-IESL on year 2003, and shortly after he established the PMDL in the premises of FORTH. He has been heavily involved in the European Platform Photonics21, while also chaired the national platform PhotonicsGR. He has been involved into several research projects (European, national, industrial), personally attracted a total budget greater than 1.75MEuros. His current scientific interests include photonic crystal and microstructured optical fiber devices, whispering gallery mode resonators, optical fiber sensors, optofluidics/magnetofluidics and study of optical materials, laser radiation photosensitivity. He is a Senior Member of OSA.

Staff Researchers

Maria Konstantaki, PhD (Principal Application Scientist)

Maria Konstantaki

Maria Konstantaki received the B.S. degree in Physics from Crete University, Greece in 1993 and the PhD in Electrical Engineering from Strathclyde University, Scotland in 1997. From 1994 to 1997 she was a Marie Curie PhD research fellow in Strathclyde University investigating optical fibre sensors for Structural Health Monitoring applications. In 1998 she joined the Foundation for Research and Technology-Hellas (FORTH), Institute of Electronic Structure and Laser (IESL) where she now holds the position of Principal Application Scientist (ELE B’). She has been involved in research on the non-linear properties of novel materials, photosensitivity studies and grating inscription in standard and photonic crystal optical fibres. Her current scientific interests are focused in the design and development of optical fibre sensors and the endorsement of the technology by end users beyond the laboratory environment. Dr Konstantaki is an author or co-author of more than 100 journal and conference publications.

George Violakis, PhD (Distinguished Stavros Niarchos Foundation – FORTH Fellow)

Georgios Violakis

Georgios Violakis received his B.Eng. degree in Metallurgy from National Technical University of Athens in 2005, receiving an award from the Technical Chamber of Greece for his diploma work. In 2008 he received his MSc degree in Micro- and Opto-electronics from the University of Crete and in 2013 he received his PhD degree in Photonics from École Polytechnique Fédéral de Lausanne (EPFL), Switzerland. His PhD thesis has been awarded the Professor René Wasserman Award (Switzerland). From 2013-2014 he has worked at EPFL as a post doctoral researcher, investigating novel lasing materials in optical fibers, and fabricating and embedding optical fiber sensors for aviation structural monitoring. From 2014-2017 he has worked as scientific collaborator at Empa, Thun (Switzerland), working in the field of large scale laser microfabrication and in the field of acoustic sensing using optical fiber probes. In July 2017 he joined the Photonic Materials and Devices Laboratory at Institute of Electronic Structure and Lasers in FORTH, Greece. He has authored or co-authored more than 30 peer-reviewed international journals and conference publications and is co-inventor of 3 international patents in the field of acoustic sensing. His current research interests are focused in novel non-linear optical materials for use in optical sensors and devices.
