Benjamin Wetzel

Post-Doc Fellow

Benjamin Wetzel received his Master degree in Optics and Photonics in 2009 (high honors) from University of Franche-Comté (Besançon, France). His Master research, held in Prof. E. O’Reilly’s group at Tyndall National Institute (Cork, Ireland), was focused on semiconductor laser injection stabilities and dynamics. In 2009, he started a Ph.D. related to the study of nonlinear dynamics and instabilities in optical fiber propagation at University of Franche-Comté. This work, carried out at FEMTO-ST Institute under the supervision of Prof J. M. Dudley and Prof. L. Larger, involved several topics including supercontinuum generation, nonlinear and complex dynamics in fiber propagation, ultrafast optical pulse characterization as well as random processes and extreme event formation. In December 2012, he successfully defended his Ph.D thesis and subsequently started a position as CNRS Research Engineer at the same institute, working on femtosecond ablation, non-diffracting beams spatial shaping and graphene photonics. Since January 2014, he joined Prof. Morandotti’s group at INRS-EMT as a Postdoctoral fellow.
