Tunneling mediated by conical waves in a 1D lattice
A. Di Falco, C. Conti, S. Trillo
The nonlinear propagation of 3D wave-packets in a 1D Bragg-induced band-gap system, shows that tranverse effects (free space diffraction) affect the interplay of periodicity and no…
Shocks in nonlocal media
Neda Ghofraniha, Claudio Conti, Giancarlo Ruocco +1
We investigate the formation of collisionless shocks along the spatial profile of a gaussian laser beam propagating in nonlocal nonlinear media. For defocusing nonlinearity the sho…
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…
