Coherence properties of light in highly multimoded nonlinear parabolic fibers under optical equilibrium conditions
arXiv:2212.10063 · doi:10.1364/OL.483282
Abstract
We study the coherence characteristics of light propagating in nonlinear graded-index multimode fibers after attaining optical thermal equilibrium conditions. The role of optical temperature on the spatial mutual coherence function and the associated correlation area is systematically investigated. In this respect, we show that the coherence properties of the field at the output of a multimode nonlinear fiber can be controlled through its optical thermodynamic properties.
