Slow light is the field of photonics research that has to do with the manipulation of the group velocity of light in certain optical media. Although photonic scientists are used to thinking on the speed of light as a constant, certain media can exhibit strong control and tenability of this parameter. Striking experiments have been developed along the last years, showing from very slow group velocities (even close to the acoustic speed) to faster than light and even negative group velocities. We will review some of our work concerning the first demonstrations on group velocity manipulation in optical fibers, including the principles, experiments and intriguing results. Most of this work will be explained in simple terms, showing no contradiction with well-established relativity theories. The application of these results will also be addressed.



Short CV:

Miguel González-Herráez received the M.Eng. and D.Eng. degrees from the Polytechnic University of Madrid, Madrid, Spain, in 2000 and 2004, respectively. While working towards the D.Eng. degree, he worked first as a Research Assistant and then a Postdoctoral Fellow in the Applied Physics Institute at the Spanish Council for Research, Madrid, Spain, and had several long stays in the Nanophotonics and Metrology Laboratory, Ecole Polytechnique Federale de Lausanne, Switzerland. In October 2004, he was appointed Assistant Professor in the Department of Electronics, University of Alcalá, Madrid, Spain, where he was promoted to Associate Professor in June 2006. He is the author or coauthor of over 90 papers in international refereed journals and >100 conference contributions and has given several invited/plenary talks at international conferences. His research interests cover the wide field of nonlinear interactions in optical fibers.

Dr. González-Herráez has received several important recognitions to his research career, including the European Research Council Starting Grant, the "Miguel Catalan" prize for young scientists given by the Comunidad de Madrid and the “Agustin de Betancourt” prize of the Spanish Royal Academy of Engineering.
