基于光致折变介质中光子晶格作用下光孤子的基本理论模型,采用分部傅里叶 算法,研究了二维光子晶格调控下 空间孤子的形成及其传输特性。结果表明,在厄米特-高斯光子晶格中,晶格阶数、调制强度、深度显著地影 响了空间孤子的形状及其稳定性。结果对空间孤子实验研究具有重要的指导意义。

Based on the basic theory of spatial optical soliton model in photonic crystal lattice, using division Fourier algorithm, the transmission characteristics and stability of optical soliton in photorefractive and two-dimensional photonic crystal lattice were studied. The results show that in Hermite optic static, the lattice order, modulation intensity and depth significantly change the spatial soliton shape and its range of stability. It is helpful in experimental investigation of spatial soliton.
