Abstract

We analyze light self-confinement induced by multiple nonlinear resonances in a two-dimensional ${\chi }^{\left(2\right)}$ photonic crystal. With reference to second-harmonic generation in a hexagonal lattice, we show that the system can not only support two-color $(1+1)\mathrm{D}$ solitary waves with enhanced confinement and steering capabilities but also enable novel features such as wavelength-dependent soliton routing.
