Complex light: Dynamic phase transitions of a light beam in a nonlinear non-local disordered medium
Claudio Conti
The dynamics of several light filaments (spatial optical solitons) propagating in an optically nonlinear and non-local random medium is investigated using the paradigms of the phys…
On the generation and the nonlinear dynamics of X-waves of the Schroedinger equation
Claudio Conti
The generation of finite energy packets of X-waves is analysed in normally dispersive cubic media by using an X-wave expansion. The 3D nonlinear Schroedinger model is reduced to a…
Optical parametric oscillators in isotropic photonic crystals and cavities: 3D time domain analysis
Claudio Conti, Andrea Di Falco, Gaetano Assanto
We investigate optical parametric oscillations through four-wave mixing in resonant cavities and photonic crystals. The theoretical analysis underlines the relevant features of the…
Space-time nonlinear compression and three-dimensional complex trapping in normal dispersion
G. Valiulis, J. Kilius, O. Jedrkiewicz +6
In positive phase-mismatched SHG and normal dispersion, a gaussian spatio-temporal pulse transforms spontaneously into a X-pulse, underlies spatio-temporal compression and eventual…
Electromagnetic nonlinear X-waves
C. Conti, S. Trillo, P. Di Trapani +3
Nonlinear optical media that are normally dispersive, support a new type of localized (nondiffractive and nondispersive) wavepackets that are X-shaped in space and time and have sl…
