Routing of anisotropic spatial solitons and modulational instability in liquid crystals

M Peccianti, C Conti, G Assanto, A De Luca, C Umeton - Nature, 2004‏ - nature.com
In certain materials, the spontaneous spreading of a laser beam (owing to diffraction) can be
compensated for by the interplay of optical intensity and material nonlinearity. The resulting …

Modulational instability in nonlinear saturable media with competing nonlocal nonlinearity

CB Tabi, H Tagwo, TC Kofané - Physical Review E, 2022‏ - APS
The modulational instability (MI) phenomenon is addressed in a nonlocal medium under
