中文摘要： 实现全光网络的关键是光开关和光控制技术。而空间光孤子在实现全光控制技术中扮演重要的角色。本项目以Ginzburg-Landau方程为基础的耗散系统为背景，研究耗散空间孤子的动力学特性以及在全光控制中的应用，主要内容包括：（1）相位调制对耗散孤子相互作用（即孤子碰撞）的研究；（2）引入塔形和锥形折射率调制下，我们首次发现了耗散空间孤子的"连续繁殖"动力学特性的物理机制研究；（3）（3+1）维Ginzburg-Landau方程中时空涡旋孤子稳定性以及折射率调制下的涡旋动力学研究。本项目为设计和探索以耗散系统为基础的孤子光学器件提供新的途径和思路

英文摘要： The key technique of All Optical Network is the optical switch and controlling of optics. The spatical optical soltion will plays an important role in achieving the All optical controlling. Based on the complex Ginzburg-Landau equation as a dissipative system, our searches in the item mainly focus the dynamics of dissipative spatial solitons with numerical simulation. The summarized results are listed as follows: (1) The study on the controling of interaction between dissipative soliton (collisions of soliton) with variation of relative phase of solitons, in the cubic-quintic complex Ginzburg-Landau equation without viscosity. (2) By inducing tower-shaped or taper-shaped potentials in the two-dimensional complex Ginzburg-Landau equation with the cubic-quintic nonlinearity, we will study the novel dynamics of continuous generation of dissipative soliton. (3) In the (3+1)D complex Ginzburg-Landau equation, we numerically solve the stability vortex soliton. By also inducing the tower-shaped and taper-shaped potentials in the (3+1)D complex Ginzburg-Landau equation, we research the dynamics of vortex. This item will provides new approachs and trains of thought for studying and designing optical device of soliton based on dissipative system.
