Προσωπικό Προφίλ

Andreas Othonos received his B.Sc. in theoretical physics (1984) and M.Sc. in high-energy physics (1986) from the University of Toronto. In 1990 he has been awarded a Ph.D. degree by the University of Toronto for his work in the area of Ultrafast Laser Semiconductor Interactions. His experimental research was conducted between 1986-1990 at the University of Toronto, the Ontario Laser and Lightwave Research Centre and the National Research Council of Canada (NRC). From 1990 to 1996 he has been with the Ontario Laser and Lightwave Research Centre at the University of Toronto working on ultrafast dynamics in semiconductors and fiber Bragg gratings. Since 1996 he has been in the Department of Physics at the University of Cyprus. He is also the Head and Principal Investigator of the Laboratory of Ultrafast Science. His current research interest involves Ultrafast Carrier Dynamics in Semiconductors and Nanostructures, Optoelectronics, Nanotechnology, Laser-matter Interactions, Non-linear Optics, and Fiber Bragg gratings. Dr. Othonos is the author of one book and over 160 journal papers. He participated in number of research programs in Europe and a number of research programs from Research Promotion Foundation of Cyprus. With the help of several competitive infrastructure grands that he has been awarded Dr. Othonos created the Laboratory of Ultrafast Science (http://ultrafast.ucy.ac.cy/) that consists several state of the art ultrafast laser amplifiers utilized in studying fundamental processes and interaction in novel materials on the ultrafast time scale.
