Abstract

We address the properties of two-color localized nonlinear modes supported by one-dimensional chirped photonic lattices imprinted in quadratic media. The impacts of chirp rate and phase mismatch on the two-color solitons are investigated. Various families of two-color soliton solutions are found. In contrast to the unchirped lattices, chirped lattices can enhance the stability of two-color solitons. Odd solitons can be completely stable provided that the chirp rate exceeds a critical value, even for varying phase mismatches. We also study the excitation, unpacking, and oscillation of two-color solitons in chirped lattices. Our results may enrich the potential applications of two-color solitons in all-optical communications.
