The year 2021 represents 60 years since the birth of nonlinear optics, and with continued developments in sources, materials, and waveguides, the field is more active than ever. An area of much recent interest is the study of extreme nonlinear propagation in optical fiber and fiber lasers, and experiments have revealed a rich landscape of complex interactions due to the interplay of nonlinearity, dispersion and dissipation. In the past, however, these dynamics have not been able to be measured, but new techniques have opened up the possibility to analyze a range of novel nonlinear processes, including the generation of spontaneous “rogue wave” events with analogies to giant waves on the ocean.

In this webinar hosted by the Fiber Modeling and Fabrication Technical Group, Prof. John Dudley (Université de Franche-Comté, CNRS Research Institute FEMTO-ST) will introduce the field, give an overview of the measurement techniques used, and describe how machine learning is providing new insights into these dynamics. The webinar will be of interest to all who wish to learn about this exciting area of research.
