Observation of a gradient catastrophe generating solitons
Claudio Conti, Andrea Fratalocchi, Marco Peccianti +2
We investigate the propagation of a dark beam in a defocusing medium in the strong nonlinear regime. We observe for the first time a shock fan filled with non-interacting one-dimen…
Nonlinear management of the angular momentum of soliton clusters
Andrea Fratalocchi, Armando Piccardi, Marco Peccianti +1
We demonstrate an original approach to acquire nonlinear control over the angular momentum of a cluster of solitary waves. Our model, derived from a general description of nonlinea…
Complex dynamics and configurational entropy of spatial optical solitons in nonlocal media
Claudio Conti, Marco Peccianti, Gaetano Assanto
Intense light propagating in a nonlinear medium can generate an ensemble of interacting filaments of light, or spatial solitons. Using nematic liquid crystals, we demonstrate that…
Spatial solitons and modulational instability in the presence of large birefringence: the case of highly non-local liquid crystal
Claudio Conti, Marco Peccianti, Gaetano Assanto
With reference to spatially non-local nematic liquid crystals, we develop a theory of optical spatial solitons and modulational instability in anisotropic media with arbitrarily la…
Signal processing by opto-optical interactions between self-localized and free propagating beams in liquid crystals
Alessia Pasquazi, Alessandro Alberucci, Marco Peccianti +1
The reorientational nonlinearity of nematic liquid crystals enables a self-localized spatial soliton and its waveguide to be deflected or destroyed by a control beam propagating ac…
Observation of optical spatial solitons in a highly nonlocal medium
Claudio Conti, Marco Peccianti, Gaetano Assanto
We report on the observation and quantitative assessment of self-trapped pulsating beams in a highly non-local nonlinear regime. The experiments were conducted in nematic liquid cr…
