ORC Seminar Series

Professor John Dudley
University of Franche-Comté, Besançon

Date: Wednesday 31 October 2007
Time: 2pm
Venue: Building 44, Lecture Theatre A (Room 1041)

Since its first observation in 2000, supercontinuum generation in photonic crystal fibre has been reported under many different experimental conditions and by many different groups worldwide. In this talk, we will review supercontinuum generation in highly nonlinear and photonic crystal optical fibers and present an overview of the underlying spectral broadening processes. We will emphasise the supercontinuum stability properties, and discuss selected design criteria allowing supercontinuum spectra to be tailored to particular applications. In addition, a selection of recent developments identifying new dynamical interactions and frequency conversion mechanisms will be presented.

Originally from Otahuhu in New Zealand, John Dudley received B.Sc and Ph.D. degrees from the University of Auckland in 1987 and 1992 respectively. In 1992 and 1993, he carried out postdoctoral research at the University of St Andrews in Scotland before taking a lecturing position in 1994 at the University of Auckland. In 2000, he was appointed Professor at the University of Franche-Comté in Besançon, France, where he heads the Optoelectronics and Photonics research group. He was named a member of the Institut Universitaire de France in 2005 and elected a Fellow of the Optical Society of America in 2007.
