Idealized four-wave mixing dynamics in a nonlinear Schrödinger equation fiber system

If the behavior of a pendulum oscillating with a low amplitude is easy to predict, this is no longer the case when the energy transmitted to it increases. We then enter the world of non-linear physics which requires more advanced conceptual tools and which potentially leads to chaos. Photonics and more specifically optical fibers are a remarkable solution for experimentally studying such behavior: the evolution of light during its propagation is indeed similar to that of a non-linear oscillator.

As part of a collaboration between the Laboratoire ICB and the FEMTO-ST institute, a team of researchers has, for the first time, demonstrated the ideal behavior of such an oscillator. This was made possible thanks to the development of a brand new experimental device which precisely records the properties of light and allows perfect observation over distances of several tens of kilometres. Fundamental physical properties theoretically predicted 30 years ago have been fully and rigorously confirmed. The observations made should have a significant impact, whether at the fundamental level for a better understanding of rare and extreme phenomena or at the applied level in the design of better optical amplifiers.
This work has been published in the prestigious scientific journal Optica.
