研究了二次介质中一维啁啾光子晶格支持的双色局域非线性模的性质。研究了啁啾速率和相位失配对双色孤子的影响。得到了双色孤子解的各种族。与非啁啾晶格相比,啁啾晶格可以提高双色孤子的稳定性。奇孤子可以是完全稳定的,只要啁啾率超过一个临界值,即使有不同的相位不匹配。我们还研究了啁啾晶格中双色孤子的激发、解包和振荡。我们的研究结果丰富了双色孤子在全光通信中的潜在应用。
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.
