摘要 基于二维非定域非线性介质中的库默模型,研究了库默孤子的传输特性。分析发现,存在一群二维库默-高斯孤子簇,如环形孤子、项链孤子和半月形孤子。数值模拟表明高斯孤子和环形孤子是稳定的,其他孤子是不稳定的;并且非线性调制系数、调制深度等参数对孤子传播特性有着重要的影响,随着它们的增加,孤子的稳定性增加。 Based on Kummer model in nonlocal nonlinear medium, we study transmission characteristics of Kummer soliton. The results show that there is a group of two-dimensional Kummer-Gaussian soliton clusters, such as ring solitons, necklace solitons and lune solitons. Numerical simulation shows that Gaussian solitons and ring solitons are stable, while other solitons are not stable. Nonlinear modulation coefficient and modulation depth parameters have an important influence on the stability of the soliton, with their increase, the stability of the soliton improves
