Mesoscopic correlations in nonlinear disordered media
Nonlinear disordered media, such as random assemblies of LiNbO₃ nanocubes, exhibit unique statistical properties arising from the interplay between second-harmonic generation and extreme scattering conditions.
In collaboration with Frank Scheffold, Romain Pierrat, and Arthur
Goetschy, we show that the combined effect of nonlinear light generation
and strong scattering induces significant correlations in the photons
propagating through a nonlinear disordered medium. In this regime,
photons no longer travel independently but instead follow nearly
identical routes. This work is an important step toward understanding
light transport in nonlinear disordered systems, an emerging platform
enabling broadband second-harmonic generation and large-scale photonic
computing.
