Toward quantum-noise-limited interferometric measurements of optical nonlinearity in vacuum
Ali Aras, Adrien E. Kraych, Xavier Sarazin +3
Quantum Electrodynamics predicts that the vacuum must behave as a nonlinear optical medium: the vacuum optical index should increase when it is stressed by intense electromagnetic…

Statistical properties of nonlinear stage of modulation instability in fiber optics
Adrien Kraych, Dmitry Agafontsev, Stephane Randoux +1
We present an optical fiber experiment in which we examine the space-time evolution of a modulationally unstable plane wave initially perturbed by a small noise. Using a recirculat…
