Abstract
We study the impact of temporal randomness on the formation of vectorial dispersive shock-waves that emerge due to the interaction of a partially coherent probe wave co-propagating together with an orthogonally polarized intense short pulse. Experiments carried out in a normally dispersive optical fiber demonstrate that the lack of coherence of the probe landscape acts as a strong diffusive term, which is able to hamper or inhibit the vectorial shock formation.
Highlights
In the last decades, shock waves have been the subject of intense studies in many areas of physics, ranging from hydrodynamics, nonlinear optics, condensates or plasmas [1]
We provide here a set of experimental results carried at telecommunications wavelengths that have been closely confirmed by numerical simulations based on two coupled nonlinear Schrödinger equations corresponding to a simplified Manakov model [5]
We first recall the basic principle of the vectorial interaction through XPM between a weak CW probe copropagating in an optical fiber together with an
Summary
Shock waves have been the subject of intense studies in many areas of physics, ranging from hydrodynamics, nonlinear optics, condensates or plasmas [1]. In nonlinear optics, a self-defocusing regime of propagation can turn the front of an initial pulsed signal into a gradient catastrophe which is regularized by chromatic dispersion.
