Research Topics

My research focuses on the fundamental investigation of nonlinear effects in tiny optical fibers (fiber tapers, photonic crystal fibers) and their applications to all-optical signal processing for future ultrafast telecommunication systems, fiber lasers, optical fiber sensors, spectroscopy, and metrology. My work is more specifically devoted to the following topics:

  • The Brillouin light-sound interaction in microstructured optical fibers and optical nanofibers,
  • The supercontinuum generation from ultraviolet to mid-infrared in optical fibers and photonic crystal fibers,

  • The development of ultrafast fiber lasers using novel mode-locking techniques based on solitons and four-wave mixing,

  • The study and design of fiber optical parametric amplifiers for telecommunications and other applications,

  • The nonlinear dynamics of spatial optical solitons in nonlinear Kerr media,

You may further find detailed informations on these topics in our journal and review papers. Most of these research works have been funded by grants from several national and european agencies and 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, _site, EUR, CEA, Alcatel-Lucent). Our group is also working closely on these topics 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, Germany, Tampere University, University of Maryland, USA,..).
