Parametric Solitons in Two-Dimensional Lattices of Purely Nonlinear Origin
Abstract
We demonstrate spatial solitons via twin-beam second-harmonic generation in hexagonal lattices realized by poling lithium niobate planar waveguides. These simultons can be steered by acting on power, direction, and wavelength of the fundamental frequency input.
