Red solitons: evidence of spatio--temporal instability in ${\chi }^{(2)}$ spatial-soliton dynamics

Stefano Minardi, Giovanni Blasi, Paolo Di Trapani +4

In ${\chi }^{(2)}$ three-wave mixing, the noise-seeded spatio--temporal modulational instability has a dramatic impact on the spatial-soliton dynamics, leading to the counterintuitive ob…
