摘要

研究了含双波导的二次非线性晶体中脉冲对的形成和传播过程，研究了不同参数下的脉冲对的形成和传播过程，这些参数与波导的相对位置、脉冲之间的延迟和相位比有关。在波导接近过程中，脉冲的传播模式发生了变化，并且脉冲之间的相互作用依赖于初始相位比。

(2 + 1)D Soliton Pairs in a Planar Quadratic Nonlinear Crystal with Inhomogeneity

The process of formation and propagation of pulse pairs in a quadratically nonlinear crystal with two waveguides was investigated with varying parameters related to the position of the waveguides relative to each other, delay, and phase ratio between pulses. A change in the pulse propagation mode during the approach of waveguides and a dependence of the interaction between the pulses on the initial phase ratio were found.
