Researchers have observed two-color optical solitons in a 2D parametric photonic lattices (PPLs) with hexagonal symmetry in lithium niobate. PPLs behave as uniform and homogenous dielectrics under weak excitation whereas, at high powers, they allow for the simultaneous quasi-phase-matching of several susceptibility processes. It has been observed that 2D PPLs support novel simulation space dynamics through twin-beam second-harmonic generation. In the symmetric configuration, solitons can form in an enhanced spectral range for confinement, while in the asymmetric cases, they can be steered by varying the input power and wave-length. Quadratic spatial solitons in planar nonlinear lattices unveils new opportunities for physics and also enable applications of self-trapped light beams, including the engineering of solitons states for analog signal processing and all-optical switching/routing in aperiodic lattices and quasi-crystals.
