摘要
采用自相似方法,时空调制的光子晶格广义变系数的非线性薛定谔方程化简为常系数方程,将相关的表达式代入原方程,得到了不同传播形式的精确孤子解,并详细讨论了周期性分布的亮、暗呼吸子的传输性质.
A self-similar transformation method is utilized to reduce the generalized nonlinear Schrodinger equation(NLSE) with variable coefficients to the standard NLSE in space-time modulation photonic crystal lattice,whose soliton solutions are then transformed back into the solutions of the original equation. Special kinds of explicit solutions, such as periodically breathing bright and dark solitons, are discussed in detail.
