Welcome to my homepage

I am a CNRS scientist in photonics at the FEMTO-ST institute in Besançon in France and I am leading the nonlinear photonics group within the Optics Department. In our group,  we investigate both theoretically and experimentally fundamental nonlinear optical effects that occur in specialty optical fibers with the aim of investigating potential applications to ultrafast signal processing, fiber-based telecommunications, fiber lasers and optical fiber sensors. Our group has broad expertise in nonlinear fiber optics and related fields and we have done many scientific achievements in the fields of broadband fiber-based parametric amplification, supercontinuum light generation, Raman fiber lasers, passively mode-locked fiber lasers, and Brillouin light scattering in specialty optical fibers and related devices. I co-authored more than 110 publications in scientific journals and as many conference papers. You may further find detailed informations in my Google scholar or ORCID I supervised 16 Ph.D Students, Postdoctoral researchers, and postgraduate students. I am also working closely with a number of industrial and academic collaborators in France and abroad (ULB Bruxelles, EPFL, Lausanne, McGill University, Montreal, University of Auckland, NZ, Max Planck Institute, Erlangen, University of Maryland, USA, DTU Fotonik, Danemark, TUT, Finland,...).

My current research involves the nonlinear interactions between light and condensed matter and their applications - particularly through the use of optical fibers and related tiny waveguides such as photonic crystal fibers, optical nanofibers, and micro-resonators. We are specifically working on the following research topics:

• Investigation of optomechanical interactions and Brillouin scattering in optical nanofibers and microstructured fibers
• Development of supercontinuum fiber sources from the ultraviolet to the mid-infrared wavelength range,
• Design and development of ultrafast fiber lasers using novel nonlinear mode-locking techniques,
• Investigation of ultrafast noise dynamics in nonlinear fiber optics and fiber lasers,
• Design and development of ultrafast fiber lasers using novel nonlinear mode-locking techniques,

Most of these research works have been funded by many grants from several national and european agencies and in collaboration with several industrial partners (European H2020-MSCA-ITN, French research minister, ACI and ANR, CNRS, LABEX Action, European INTERREG Programme, FEDER, Bourgogne Franche-Comté Region, University of Franche-Comté, I-site UBFC, EUR UBFC, CEA, Alcatel-Lucent, Leukos Optical Systems, NKT Photonics).

I am a member of The Optical Society of America and of the IEEE Society and the French society of optics (SFO). In 2012, I received the Fabry-de-Gramont award from the SFO for scientific achievements in the field of nonlinear photonics.

I have been fascinated by laser and optical science since an early age and I haven't looked back since ! As a scientist who plies my trade to photonics research and innovation, I never cease to be inspired by the exceptional creativity of great physicists of the past whose works and ideas were unremittingly brilliant in the whole history of human thoughts. I am also passionate about photography and especially for science and research (See below one of my first pictures in laser science taken in 2003).
