Welcome to my homepage

Hello, My name is Thibaut, I am a CNRS scientist in the photonics laboratory at the FEMTO-ST institute (Université Bourgogne France-comté, UBFC) in Besançon, France. I am currently working in the nonlinear photonics group, and we investigate both theoretically and experimentally fundamental nonlinear optical effects that occur in specialty optical fibers and other tiny waveguides with the aim of investigating potential applications to all-optical signal processing, fiber-based telecommunications, narrowband coherent and broadband supercontinuum 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. You can access and read our peer-review articles from my Google scholar or my ORCID.

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 ideas were unremittingly brilliant. I have been fascinated by laser and optical science since an early age and I haven't looked back since ! I am also passionate about scientific photography (See below one of my first pictures in laser science taken in 2003). I am teaching nonlinear guided optics and its various applications to Master and Ph.D students. I also supervised 16 Ph.D Students and all of them have successfully graduated and got a good job afterwards in academics or industry. 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.

My current research involves the nonlinear interactions between light and condensed matter and their applications - particularly through the use of various glass-based 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:

• Development of supercontinuum fiber sources from the ultraviolet to the mid-infrared wavelength range,
• Investigation of optomechanical interactions and Brillouin scattering in optical nanofibers and microstructured fibers,
• Design and development of ultrafast fiber lasers using novel nonlinear mode-locking techniques,
• Measurement of real-time ultrafast nonlinear dynamics in nonlinear fiber optics and fiber lasers,
• Development of fiber-based optical parametric amplifiers and Raman fiber lasers for optical communications,

Most of these works is carried out with a number of industrial and academic partners 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, University of Warsaw, etc...).

Our research projects 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).
