Frédéric Smektala receives the degree of engineer in chemistry in 1989 at the Ecole Nationale Supérieure de Chimie de Rennes, supplemented by a DEA in solid-state chemistry at Rennes University, France. Then he engages himself in the field of scientific research and gets a PhD in Physics-Chemistry in 1992, for his work on halide glasses infrared optical fibers. He continues his activity during a post-doc with Alcatel Alsthom Research Laboratories through the European Race Gain project (Glass Amplifier for Integrated Network). In 1994, he joins the University of Rennes staff as an assistant-professor and becomes full-professor in 2002. In 2006, he moves to the University of Bourgogne in Dijon, France, and joins the SLCO team (Solitons Lasers and Optical Communications) at the ICB Lab (Laboratoire Interdisciplinaire Carnot de Bourgogne, UMR CNRS 6303) to further develop his research work within a team of expert people in the field of nonlinear effects in optical fibers.

He leads a research activity in the area of unconventional infrared vitreous materials, the development of optical fibers based on these glasses, and applications of these glasses and optical fibers in active or passive devices. Various glassy systems are considered: halide glasses, chalcogenides, chalcohalides, oxy-halides, phosphates. Optical amplification properties and nonlinear optical properties of these glasses and optical fibers are more particularly explored. The optical amplification is interesting for multicolor telecommunication networks and wavelengths multiplexing, where it is necessary to have broad band amplification.

The nonlinear optical properties (particularly cubic ones) are interesting in the context of ultrafast optical switching and more generally in signal processing operations. The recent advent of photonic crystal fibers, exacerbating the nonlinear properties of a waveguide, further enhances the interest in the study of non conventional glasses intrinsically more nonlinear than silica glass. To get the control of the elaboration of micro structured optical fibers from chalcogenide glasses or heavy oxide glasses for example lets consider innovative applications in the mid-infrared, beyond 2μm, such as for example supercontinuum generation in the 3-5 µm atmospheric transparency window.

More generally speaking, microstructured fibers from infrared nonlinear glasses allow to imagine the realization of fibered broadband sources in the mid infrared (2-10 µm). These new sources could be implemented in various devices for medical, biomedical, environmental or military applications, to fit with the demand of the society in the fields of security, human health and well-being.

Frédéric Smektala has published around 120 articles and conference papers and has given around 40 talks in international conferences, including a dozen of invited talks.
